Sorry for the late reply! From what we can tell this is probably a false positive which seems to happen occasionally with Ren'Py games. Could you send us a list of the affected files to email@example.com so we can see if there is something we can do to prevent this?
And thank you so much that you want to buy the full game! It will still take a bit until it's finished because we first want to finish the second half of our other game //TODO: today but you can follow our development progress on our devlog here on itch and our blog!
