PureBDCraft 256x: blockstate .json files missing

[joyoustoothaches]

I recently downloaded PureBDCraft 256x and the blockstate .json files for the new blocks added in 1.17 are missing. The textures themselves are there, but the .json files are missing for blocks like copper (the ore and the block) and deepslate are missing and causing the textures to show as default in-game. The pack (and all addons) also show as being for 1.16 in the resource pack menu despite the folders and download being titled as 1.17.

I've tried redownloading the pack with no success. Have other people had the same issue? Is there a fix for it?

Blockstate files aren't necessary in a resourcepack.

It really doesn't make sense that you downloaded the MC1.17 files, but the game is saying they're wrong.

Can you take a screenshot of your resourcepacks screen?
Can you also press the "Open resourcepacks folder" and take a screenshot of that?
