Pin detect error on TL866II Plus and GAL16V8/GAL20V8

When I try to program or read a GAL16V8B or GAL20V8B I got pin error on pin 2, if I ignore it, it works fine. During the first reading or programming it usually works without any errors, but if I try to read or verify a chip directly after programming, I got this error. I've tried a few different chips. In TL866A there are no problems with the same chips. Programmer's self-test shows no errors, and chips are programmed fine, even with the error present and ignored.

GAL22V10 seem to work fine, no errors there.
