Run the clean task and try again. If that doesn't work try compiling a mod jar and running it on a normal Minecraft installation.

SmushyTaco · 2021-10-25T21:37:10Z

After some testing I've done myself with the compiled jar I'm seeing no issues. I don't believe this is an issue with the template itself. Please go to the Fabric discord and request support there.
