Some Education Edition blocks do not accept PBR textures through subpack, this report should be closed. things function as they should.

I'm sure that all files are fine (I fully understand PBR textures & have been working with them for a long time), This should Logically work if put in Textures -> Blocks folder Just like Element blocks, Element blocks can take PBR textures, tried for other Education edition blocks than elements & It's not working, as Education edition blocks are all stored in one place, I expect it to work the same way as Element blocks.

this was the result:

As you can see, they have NO pbr properties, the first black element block is Supposed to work & have some bumpy textures, the other ones are supposed to have some glow & reflectivity as Iron, It doesn't give me missing textures meaning that GAME DOES NOT EVEN READ THE FILES FOR THESE TEXTURES, hopefully mojang fixes this.

As for the list of blocks that are not being accepted by game:
Simply: All None Element blocks Excluding the Mystery❓ element block or element_000 are affected.

just to clarify: I can actually change & give pbr support to all 

EDIT: AFTER FURTHER INVESTIGATION, can confirm that this ONLY & ONLY happens IF resources are in a Subpack!.
I can confirm sub packs are working correctly, Took the exact textures out of sub pack & it worked!|
EDIT2:  FIXED IN THE LATEST BETA
