It keeps spamming that fabric:pickaxes, fabric:hoes, fabric:shovels, etc. are specified as item verifier tags but do not exist.
This is not with a custom datapack and seems to happen with a ton of different mods.

Using more mods and custom datapacks, the same thing happens but with even more spam for other pieces of gear.

Here's a couple logs. In the first one, it was caused by BetterNether but in the second one I realized it happens from a lot of different things.
t.log
latest.log

Is there a way to fix this or is it a bug? And is it something to worry about?
