Why does the Cleanse Corruption Upgrade Finder want to cleanse all my gear?

I tried it on my Raid Tanking - Heroic, Mythic+ regular and my Horrific Vision setup, which is basically Mythic+ all offense and in each case, it comes back with a list of all of my corrupted items suggesting that cleansing all 3 main hand weapons and everything else would up my score considerably.

Maybe I just have lousy corruptions, but that seems wrong.

When I try it, it says not to cleanse anything:

Hahaha, I have no idea now. Sorry for the distraction.
