I installed and ran the latest RC. First run found 440 errors, removed 221, corrected 0. Subsequent run found 16 errors, corrected 7. And every run after that found the same 16 errors and reported that it corrected 7. The last run said it found these 32 keys which are the same as it found and reported as 16.
The keys it never deleted and kept coming back are:
