If you make a datapack, go into the data folder, then go into the "sub-datapack" folder, go into functions, and then add a .mcfunction file, any other functions in that folder that have any text in them no longer show up in Minecraft at all and do not work.
Please fix this. I'm trying to make a hunter/runner datapack and its getting really annoying trying to do anything and it not working for no reason.
Please check the console for any error messages.
