Blank files that won't go away

Hey everyone, need help. I'm getting irritated at these random blank file "images" that appear. I've gone throuh to remove the month to transfer to hard storage (can't stand the cloud), and these are undeletable and very annoying to have stick around. 

I've tried looking at the originals to see if there's blank previews, but no luck.

I've also tried finding it in the web browser variant of the cloud storage, they don't show up there. 

Any help? Thanks.
