Hi team.
Definetly the Unit Tags don't work at all :)
When I set up on the front end editor and i choose one of the category that never works, sometime that set up a random number, sometime that set up "Select Category". I can't make it stay on the good category.
When I set up the unit tag on the back end editor, that seems to work but in reality not.
Because the tag do not agroup all the units and if a trainer make a modification on the front end editor that reset the unit.
I think the "Module-tag" not works right.
Yes this is already a known issue and already present in our issue log.
