Its not on your end, its on Gumi's end. The server isn't registering that the boss is already killed. Killing the boss multiple times won't helped since it'll just restart the whole server-register thingy again. After killing the boss once, just move away from the boss tile and open your talk screen and just wait it out. Or move around the map and collect items, just don't go into the boss tile and fight it again. It'd be nice if your fellow raiders in the quest know this as well.

Note: This isn't a 100% solution, its also luck based but this is currently the best one we have until Gumi fixes their servers. Even accomplishing quests in raids is RNG based.
