SM_Door does not fit in SM_Door_Frame

I’m new in Unreal Engine. I am trying to make a usable door but i cant fit the SM_Door in the SM_Door_Frame appropriately. There is a gap between them… The other choice i have is to make the SM_Door bigger by using scaling ( R ), but it is something i dont want, because door will not fit in frame too.
Is there something i can do?

In docs.unrealengine.com i saw how to set up a door walkthrough and the door fits appropriately pretty much by default!
