My Upcoming Issues Since 10.11.0

[huss]

Hi 
I have jellyfin 10.11.4 installed  on debian bookworm metal install and since jellyfin 10.11.0 I have had issues, my upcoming will show but not all and after I add a show and refresh, it disappears from upcoming instead of showing its been filled. I made a post a month or so back and was advised to clean and rescan steps which i believe i tried but it didn't change anything. now my upcoming isn't showing any shows at all as if nothing new is coming out but i know there is still episodes left on some of the shows i have.

not sure why and wondering how can i fix this. 
The only option i am looking at is doing a clean install of jellyfin and then restoring cache so i get my users and their watch list etc back, but if there is something else i can do without doing a clean install would be good know. also worried that a clean install might not fix it. 

I should also add that now i am using nginx proxy manager as my reverse proxy since it was changed from the old jellyfin.conf location before 10.11.0 just wondering is that is possibly a reason or not. cause if it could be i would just create the reverse proxy on the server with nginx i guess, not show just thinking out load.

if anyone has any ideas it would greatly be appreciated.

Thanks
