Screenshots from non Steam games disappearing

So usually, I take screenshots through Steam but if I have a game that’s not with Steam I usually add it as a non Steam game to use the screenshot function. After a little bit those screenshots disappear though, so when I highlight a game the screenshots that I’ve already taken aren’t there anymore. If I look in the place where screenshots are kept in Steam, they’re still there in one of the folders, but taking any more will create a new folder for them, so some of the non Steam games I have added will have 2 or 3 different folders for screenshots. Anyone know why this is happening and if there’s a way to fix it?

I’ve encountered a similar issue before, usually steam for what ever reason removing my non steam games. But making sure all the information matches when I add the shortcuts back seems to work (folder location etc) Though not always sadly, not sure if there is a proper fix for it.
