Please install the latest possible version:

https://www.hdsentinel.com/beta6/hdsentinel_pro_setup_6104-cmhs.zip

which has some updates for these special Kingston models. As described in the list of updates:

https://www.hdsentinel.com/beta6/hdsentinel_beta_revision.txt

- improved reporting of some Kingston SSDs (some firmware versions may previously reported high number of communication errors)

Some firmware versions work differently than others and the updated version will "know" this and not report communication errors.
Still collecting information about these special firmware versions so if you use Report menu -> Send test report to developer option, it helps checking and further development.
