Blue Key Door not properly working

[Sufferer]

i was working on a map in Doom Builder X and I've encountered something weird. when making a blue key door it will instead lower to wall that is not part of the door. 

this has never happened to me before and i'm just kinda baffled

 

(i'm testing this level in chocolate doom btw)

You're using a SR type action with a tag of 0, that means that this action will affect all sectors with a tag of 0. You either have to use one of the DR type actions or give the door sector a tag (and the line the same one).
