Sonarr only deletes download if seeding is 0

Sonarr version (4.0.14.2939):
x64-7.1_20241121-5:
Synology DSM:

Sonarr has recently stopped deleting downloaded files and I can not pinpoint the change. Sonar works as it should apart from deleting the downloaded file. But it will delete it if I set seeding time to zero inside download station.

Download station set to 0 seed time and Prowlarr / Sonarr set to 0 seed time, it downloads and MOVES the file as soon as downloading complete (so i don’t think its a permissions issue)

Download station set to 1hr seed time and Prowlarr / Sonarr set to 0 it downloads and COPIES the file after 1hr seeding.

Download station set to 0 seed time and Prowlarr / Sonarr set to 1 hr it downloads and MOVES the file as soon as its done downloading (like its ignoring the seed time request from Sonarr / Prowlarr)

log file before it completes:
