User Verification Version 2.0.46 – Delete interval unverified users not working

Please help. I have tried various time increment settings to delete unverified users, but everyday I am deleting from 2-10+ users who register and are not legitimate customers.

Also when I setup Users for support purposes, I am unable to verify them.  There is a User "john.hughes" who I try to mark as verified, but it doesn't change the Users status. There are currently 14 unverified users who should be deleted except john.hughes
