Uh... weird hierarchy rank name problem

So, I run a tribalish FC, and we like to make our rank names have that feel. We were introducing a master crafter rank, which I would like to call "Totemnic". We really liked that.

Unfortunately, it told me there was a banned word in Totemnic. Which seemed strange, so I tried Totemnal. That was also banned. So I just tried "Totem". And that was banned.

I don't know why "Totem" is banned as a rank hierarchy word, considering how many EX trials drop totems, so I can only think that there's some kind of other word blocking this? Is there a way to override this so "totem" isn't banned? That seems really weird to me.
