Filename question

Hello, I've searched, cant find answer even though I'm sure its been discussed before. Sorry.
Here is my question. For some reason, my filenames are getting suddenly messed up. For years, I download a movie, and it shows up on drive properly as "movie" (whatever movie or show title is). Now, it is being downloaded as "11c1ada261c24086885369675dfc9281.part45" etc...
I don't understand what I mangled. It looks like there is a movie name attached to the true encoded filename, and it is saving the encoded name in the directory. Don't want this, it's creating chaos on my drives. I do have a follow up question to this, but I'll start here first. Thanks all in advance.
