This type of situation has occurred hundreds of times in the pgn downloads of CCRL and CEGT, and will keep on occurring unless corrected.

I am just interested in identifying the gui(s) that do this. I have software that can correct the situation, but I do want to know which gui is doing this so that perhaps they will correct their bug.

Here are 2 examples, the first from CEGT, and the second from CCRL. In the first, I removed the comments. These games are very recent.

I have put in a comment at the top of each game that notes the move whose notation I am questioning.
