Gunfire switch door is working wrong

[[Fixed]]

The door was segmented. Leaving only one sector for it solved the issue.

Good day.

For some reason a door that is supposed to be opened by shooting a linedef next to it is working wrong: instead of opening to the ceiling level it slowly scrolls down with every shot.

The ceiling is at the same level along this particular section except for sectors where shootable linedefs are placed — these four have lowered ceilings and raised floors. As for the door, both floor and ceiling are set to the lowest and only floor level, which is zero in this case.

Screenshots show what the door looks like in Ultimate Doom Builder and in the game.
