A workshop bug when declaring victory

Ill keep it simple. I cant declare victory in the team deathmatch mode using “Declare team victory”.
I could at first, but it just stopped working.
I tried using the skirmish mode and there i could but when i tried to revert to team deathmatch,
it just doen’t react. It shows up in the inspector, says it executed the action, but doesnt actually end the match.

Help?

Thanks in kind.
