Rotated Trapdoor generates incorrectly (Addon)

When I try to generate survival outposts, I came across a bug regarding trapdoors. I use those as window decorations and a flower pot.

 

I was making structures with a feature addon and a feature rule addon. The trapdoors aren't facing the correct direction due to Facing_Direction at random.

 

Observed Results: The trapdoors connected to air. A trapdoor connects to a plank block instead of a grass block, making an ugly flowerpot.

Expected Results: The Trapdoors connect virtually against any block. Another trapdoor connects virtually against a grass block as a flowerpot.
