I wasn't playing ANY ranked matches (mostly sticking with Unranked, considering you people saying about it filled with Kratos spammers and that kind of junk) yet I still get a belt. Mind explaining that bug/glitch/whatever?
Honestly, for me, those titles and belts are just pointless bragging rights.
As to the question....it could/should/would be a glitch as belts are only a ranked match thing. In unranked- they appear and disappear randomly. Ranked- there to stay- unfortunately.
