Doors seems to be buggy in general, you basically have to be in front of them to open them, instead of making the player walk over to the door and then do the action.

That's only for some doors.

I believe thats only for a few doors as @Gptaqbc said

Yeah there are some doors that requires the player to be on specific tiles for them to open/close. I think it's mainly because these doors have force-teleport effect on player or something like that.
