This same issue has been posted on here before but it appears to be a per-mod basis. I am terrible at reading logs so I decided I'd just ask here for help on reading them so I can figure out which mods have broken data packs or if its maybe a different issue all together. I've used many of these mods, even these specific versions, before but Minecraft is claiming they're for different versions in the data pack menu which confuses me quite a bit.
Heres my Mod Folder
Log posted once I can figure out how. (I'm new to Forge Forums.)
