Team blockers keep switching teams

A week or so a go I finished a map called “Tilt Table” where players try to knock each other off of a massive platform that tilts. When they fall off, they are dragged through two team blocker objects to separate the teams before they are sent to a control room. The only problem is is that the team blocker objects switch teams randomly each round between the teams that are currently playing, so don’t always let through their designated team. Any ideas how I can fix this?

Additionally the table itself was made using magnets and setting it to a welded group. Everything aligns perfectly in forge, but in custom games all of the table’s pieces have rotated very slightly. Any suggestions for this?
