Panner Appearance in Mixer, and another thing

I have no surround plugins yet my mixer panners have changed into “boxes” and one of then now shows a “mix convert V6” which I have no idea how to get rid of. I have no idea why it even showed up. See attached image. Please help.

Solved. Apparently after upgrading Kontakt to V6.6 Kontakt neglected to retain my output configuration and included a surround output - screwing up some templates. Once I resolved the Kontakt output issue (this did not occur in the Kontakt Standalone) all was well. For me it was quite a head-scratcher.
