> Find this hard to believe considering the SSD 10 year warranty.
Why?
This SSD reports the number of sectors failed - and Hard Disk Sentinel detected, reported this.
I suspect it did not write that warranty replacement is required (I suspect exactly the opposite).
> So, to fail, even if only 1 possible bad sector is highly unlikely, right?
Why do you think it is not possible to have a bad sector on SSD?
Then there would be no such attribute, showing that....
> more probable this is an error/bug with HDS?
No, of course there is not.
Hard Disk Sentinel designed to detect and report any kind of problems (even very minor ones) exactly to be notified about possible degradations of the status, and be prepared (with backup and possible planned replacement - when required.
Let me explain.
Yes, I can confirm SSDs can have bad sectors as well, exactly as hard disks.
After write to a specific sector, the SSD verifies the contents of the sector and if the CRC check shows that the written information is damaged / corrupted, the SSD automatically writes the data again to a spare sector and re-directs all further reads and writes to that sector.
This is exactly what hard disks do - just on SSDs the whole process is much quicker and there are no noticeable signs, for example no "clicking" or other weird noises, no retries / substantial delays, freezes and so.
Because of this - and the fact that all further reads/writes will never use the original (bad) sector, it is completely normal to use the device.
In normal situations, there is no noticeable signs of problems, no slowness or so.
That's why because of this very-very minimal problem, it is not possible to ask warranty replacement, as this does not mean that the SSD is failing.
(please check
http://www.hdsentinel.com/faq.php#health for more information).
Manufacturers prepared for such situations and because of the current number of problems (only 1 bad sector, which does not cause any further problems) you do not need to worry: even if the status of the SSD is not perfect, the bad sector is not accessible by any means.
I'd recommend some testing to verify if the SSD has further problem(s) or if the status is now stable and the device could be used without problems.

Now, as the current errors are already fixed and they can't cause any further troubles, you may even clear the error-counter. Then Hard Disk Sentinel will not display this problem any more and then the health also restore back to 100% and you'll be notified only about any further problems/degradations in the future (if there will be).
For this, please open the S.M.A.R.T. page of the SSD and locate the attribute
"5 Reallocated Sectors Count"
In the "Offset" column of that attribute, click on the 0 between the + and - buttons.
After acknowledging the message box (which describes that this correction may affect the display of the complete status of the device), specify
-1
(the error count displayed in the text description, just with negative sign).
After closing that window, soon the problems will be removed from the text description and the health improves back to 100%.
Note that the graph on the bottom will still show the smaller value today as the graph shows the daily lowest health measured. But from tomorrow,
it will also show 100% - until any new problem/degradation will be found with the device.
If you have an "Extreme" type SSD with larger warranty, it only means that
- the manufacturer prepared better and for example used larger spare area to allow more reallocated sectors
- the manufacturer prepared for warranty replacement for longer time and calculated the price of the SSD with that.
But it does NOT mean that one (or more) sectors can't fail, even with normal usage.
