Map boss mirage mod without an Mapboss in the mirage

Im currently Farming Citysquare for Ritual and 2 times already i got the "Map Boss is Accompanied by Ridan, of the Afarud" Mod in an kinda bugged state.
1 of the three map Bosses is inside the Mirage and the other outside. so they count as inaktive and cant be killed. i hope this is not on purpose

here youu got an screenshot of such an encounter
