Grifball Forging Help

I’m trying to make a Grifball map, but I have one major issue. No matter what I do with the goals, they don’t seem to allow anyone to score points. I’ve tried copying the goals on Hangar 101 even, and they still don’t work. Am I missing something? Is there something that the Matchmaking maps have that we do not (aside from invisible and un-forgable walls)? The ball spawns fine, and it can be picked up like normal. The only issue is with the goals.

Thanks for any help you can give!
