Didn’t receive reward for completing triage mastery challenge

I was on a run in dire marsh (night), got into a fight with a team and both my teammates got downed. Using triage’s prime ability reboot+ I zapped both of them, which should have completed the mastery challenge, I even went on to kill the rest of the team, feeling awesome. When I went back to lobby the challenge didn’t register, please fix this, it was the last challenge to complete all mastery challenges for triage. I’m owed a skin. https://youtube.com/shorts/MfAJZbu-q1Q?is=fG4tJgtskUQFTNy-
