[Dx4win] changing award flags

[K6XV]

I'm trying to clear my DXCC Mixed Submit flags by going to Reports > Change Award Flags > DXCC Mixed > Clear Submitted.  I go back in and check each call and verify the Sub has been removed and it seemed to work however as soon as I call up the DXCC Submissions Report, it resets the flags back to submitted? Why is this happening? I'm on version 7.02.02.

Thanks,
