I'll have a look, that's a weird issue.
I came back to see if the issue persists into the updated version of the game. It does. Have you encountered this issue on your end yet? If not is there any good space to share further details if you need them?
-Edit: I performed a save clean under RenPy persistent saves folder and now when loading a game I get offered the are you sure you wish to load a previous save menu as intended, I'm not sure what caused the disconnect prior but am glad I can play properly :)
