Blockcraftery Stairs don't change their orientation when I use Worldedit flip and rotate commands

[Darsilen]

General Information

Describe the bug:

I Play Minecraft on 1.12.2
I have many mods installed but they are not important to my issue.
I have Worldedit installed for 1.12.2 alongside Blockcraftery. Whenever I try to flip or rotate Framed Stairs, Framed Slant, Framed Outer Corner, and Framed Inner Corner they refuse to change their orientation. They flip and rotate, however their orientation remains the same.

To Reproduce:

1. Place Framed Stairs somewhere
2. Select it with the wand(wooden axe)
3. Type in chat //copy or //cut
4. Type //flip north or whatever direction you want or use //rotate 90
5. Once you do that type //paste
   (Sheesh, I gave a tutorial on World Edit here.)

Expected behavior:

I expected the orientation of the blocks to change. (duh)
