Simple resource packs change nothing

[AvatarNeo12]

When using a resource pack for Presence Footsteps, nothing changes when it is loaded.

I made a pack from scratch (included all necessary files and folders) and organized it exactly as the documentation for the mod describes. The only file in assets/presencefootsteps/config is blockmap.json, with a list of vanilla blocks and reassigned sounds exactly matching the formatting of the example. It is recognized by the game and loads properly.

In-game, however, nothing is different from the default Presence Footsteps. For example, I changed the sound of Warped Nylium, but it still uses the wet sounds from default PF. This applies to all blocks I changed.

I tried the following (and possibly more):

-Using different kinds of brackets in blockmap.json
-Loading as a folder and a .ZIP separate times
-Loading on separate CurseForge installations
-Unloading and reloading multiple times
-Renaming the folder from presencefootsteps to presence_footsteps
-Checking repeatedly for typos and proper formatting

The pack format is compatible with the version I tested on (1.21.1). I assume this is a bug and not a mistake on my part, but I could be wrong.
I recall finding a bug report for this from years ago, reported as fixed, but it still persists. It might be an issue only on my computer, but I doubt it.

Weird, it worked and changed most blocks, but some are still using the default (from Presence Footsteps)

These are still unchanged:

• All three Basalt blocks
• Glowstone
• Dark Prismarine
• Dirt Path
• Crying Obsidian
• Both Nether Wart blocks
• Coral Blocks (alive)
