Mismatching number of blocklist hashes detected on blockset

I am running 2.0.4.5 beta and also getting this error:

Unexpected difference in fileset version 160: 8/13/2018 7:52:24 AM (database id: 2), found 170 entries, but expected 171

I have repaired the database, but when I verify files I get the same error. There is a suggestion to take the error message’s information and run the DELETE command. Can someone explain this a bit more for me so I can fix this error? Thanks.
