Door closes itself while I'm still inside the trigger

Hi, I made a sliding door ( a brush set as func_door, sliding upwards ) and a trigger around it that sends Open when OnStartTouchAll and Close when OnEndTouchAll. But I tried staying in the trigger brush for a certain amount of time, and it will close itself and not open again until I get out of the trigger and go back in. I saw no settings on the door about this, so how do I stop it from happening?
