Trader Doors

[Fifflethecat]

Recently I found a tutorial on how to make a trader door.
I just have one small problem...It Doesn't close after the round ends!?

Upon adding the trader door, I make sure the Event and Tag for the door are correct. I also have the Teleporter outside of the door but doesn't really help since the door doesn't close anyway >.>

Trader Event: Shop
Door Tag: Shop

There is also another problem that I can't seem to figure out. How could I have multiple traders in a map with them conflicting?
