I got my first compiler kill, but no credit

I went in with my team, we teamed up with some free kits along the way and had a generally friendly lobby. We all went and killed the compiler (using my dna key that I brought), me being the leader of the group. I managed to miss the exfil in the back while admiring the scenery and looking at the little outpost pinwheels on the side of the Marathon ship. Fine, I ran back through the air lock and exfiltrated from the one before the boss room. I got credit for the Ganglion my team left with and I have the Biotoxin disinjector, but no codex entry, skin, or barter for the special weapon ammo. https://youtu.be/xzWXurKa98U
