Enabling spawners bugged?

For our map we have spawners enabling based on a trigger. We have some spawners set to a team index, and others are set to any. The spawners that are set to a team index work fine and enable when its triggered to enable. However, the spawners set to any, do not enable. The weird thing is that these spawners disable just fine. For whatever reason they just refuse to enable when called to do so. I think this is a bug because I cant see a reason why a simple trigger can’t enable the spawner, no matter if its set to team index or not. Maybe we’re missing some setting?
