Wall mod not "working"

Hey guys!
The other day I tried to apply a wall mod for my aoe3de.
I did the required steps: tools,mods,search mod(in my case a mod that makes the walls look like the ones from the campaign),subscribed to the guy’s mod,prioritized it to 1st,and clicked the bubbly thingy to make it blue. Restarted game and pc and…nada! Mod does not apply!
Checked the files(data,units,protos),it’s all there,all in order.
There is no screenshot to attach,just the wall “button” is not showing up,instead the “classic” wall button remains.
Thoughts? Please help :relaxed:
