Hey so today I was able to clear VM Colossal Monolith in 8M with my guild which was awesome, and we all got the titles but me (Inquisitor Ghost - legacy Arcx) and (Mister Leung - legacy Envoy) were not able to acquire the achievements for our first time being there and completing it. Attached are pictures 1 and 2 which show the titles acquired/defeating the monolith and the achievement not being registered, respectively.
Sorry if this is the wrong place to post this, do not use forums very often.
