Took me a sec to figure it out, but I know what is happening. The door component was the root and relative rotating the Root make the BP think the orientation is based on the world.
I was able to fix the doors by adding a Scene Component and the making that the new root. Then I set up the BP like this:
I found that even the right door would cause issues if it was facing the wrong direction, so both had to be changed to reflect this.
Let me know if that helps.
