Shares not sticking / wrong movies listed within folders

I’ve ripped my Blurays to mkv fikes and have been using Universal Media Server to stream to my PS3 successfully for years.

I recently got Infuse as I wanted to stream to my Apple TV.

It’s a great experience but lately I’ve been having some issues.

I find that I always have to delete my shares and then re add them otherwise it will say “no content” (or something to that effect)

Also - random movies will appear within the movie folder I’m trying to watch. Two examples attached. These are both from The Darkest Hour folder. Somehow Elf appears in there, then the next time I load it Dunkirk is in there! (And resuming the darkest hour file just results in a hang)

Help!
