Video files in Photos Directory

I’ve been using Plex for years to store my home videos and photos. I have one directory called Photos which should only show photos and another called Home Videos which you’ve probably guessed only show videos. Recently I’ve noticed that the Photos Directory is now displaying *.MOV/WMV/MP4 files as well as photos? Has something changed? Can I revert somehow?

On most recent Windows version of Plex.

H!

You have to 100% use correct folders to store stuff in.

Videos = videos
Picture = pictures

Within PLEX you have to make sure to put the correct folder behind each single media-linear.

While using inconsistent folders and/or media-libraries it will not work
