Seasons not showing on TV show page

[oslohimself]

So I've tried to rename the folder like you said, and it didn't work. The only thing that changed is that even if I try to refresh the metadata and pictures, it won't load any episode pictures.



For example, on this sho,w all the episodes are named like that 



The weird thing is that I've had this server running for a few years now, and I haven't changed anything.
