#minecraft:tick is not looping

i am creating a datapack and i have a very strange bug : the #minecraft:tick function is not looping every tick

in fact, i of course created the tick.json in the (data pack name)/data/minecraft/tags/functions folder, i checked syntaxe at least 20 times, but it still don't work (i am only using stuff_like_that as namespaces)

actually, when i manually run the command /function #minecraft:tick it works as i want, but its not looping

i also tried to reload, changed stuff in the load.mcfunction (and so in the load.json) but nothing to do, it doesnt work

as long as i really can't find a mess from me, and i really searched one, i suppose it is a bug
