Other movies show up just fine in that directory. I found the issue.... The Meta tag for spongebob out of water was very very very very very very long. I used the MP3TAG program and edited the Title tag rescanned and it all works.
Yea, you wouldn't want to use FileBot (link in my signature) to name your files perfectly for Plex (in seconds) because you enjoy futzing with them constantly. You also wouldn't want to Move Local Media Assets out of the top slot in your Agent Lists so Plex won't give top priority to bogus embedded metadata because constantly futzing with your files is great fun.
Some people enjoy preparing their media once, have it instantly recognized and fully populated instantly and then watching it - but they're Pu$$ies!
