Do you have a picture of that?

Attempting to rotate the block using the Supplementaries wrench:

if you place it from a different angle does it not place it rotated?

Correct, it places facing the same direction, regardless of placement angle

which version are you on?

MC 1.20.1
Forge 47.3.0
Dyenamics 1.20.1-3.2.0

Poking at the repository myself, I can see there's no defined rotations in the blockstate for glazed terracotta.

i believe this can be fixed with just a resource pack that adds the rotations back in.
