(Apprentice) is removed

Hi all. Very new to GSE.

I have a macro in WoW, works decent:

/cast [exists,dead] Skinning(Apprentice)

I just can not get it to work in GSE.
When ever I save it, go out, and go back in, it removes (Apprentice). With out it, Skinning doesn’t work.

Is there an option or something I’m over looking?

Please help.
