CollectionService GetTagged will not work

Im literally just so confused. Im not even gonna try to spice this up or make it goofy like my other posts. GetTagged literally just doesnt work and i dont know why

local collectionService  = game:GetService("CollectionService")
local walls = collectionService:GetTagged("Wall")
for i,v in ipairs(walls) do
	print(v)
end

It literally just prints nothing, i have made sure that they are all tagged with Wall

I have turned all of my code except for this specific part into comments just to make sure that nothing else was interfering. I am going insane what the frick is wrong with this

you should probably check the parts properties to see if they acutally have the tag
