Weird files getting stuck in the /mnt/cache/local

[Playerz]

Hi

I'm using nzbget and normally i need to go into my cache location and delete files every few days because my cache fills up, sonarr/radarr says something along the lines that it doesnt have access to the files. 

so, some files makes it though no problem, then, there is some of em' that stays in the /mnt/cache/local

i point my radarr to /mnt/user/mount_mergerfs/nidhog (gdrive)/movies this is the correct way to mount it right? i do use the /mnt/user/ -> /nidhog/ 

this has been an ongoing issue for months, but just now i have had time to take a look at it.
