I didn't think this picture would be needed.

I think this is a problem. I had the same situation on my second playthrough of version 7 (in the original playthrough my Monica does not prostitute herself). In the gallery, all the scenes Ep3 v1 - Ep3 v6 are still playable, but all the scenes from version 7 (even after passing them!) don't open. Probably have to write to the developer or someone who knows about it.
In reality, the entire game gallery opens
peristant file with the corresponding entries, while editing Achievments.rpy does not give anything, it is self-defeating. After the corrections made to Achievments.rpy , the gallery icons become visible to the player, but they cannot be clicked on (nothing happens). The oddity is different. Why during the fair playthrough of the game no corresponding entry is made (apparently) in the persistent file and the desired game gallery scene from version 7 is not opened..
