Pvz Gw2 townhall community event glitch (1/12/19)

I’m playing on the Xbox pvz gw2 and I was attempting to complete the minimum kills for the community event. It said that any kill or shared vanquish would count. I played for about an hour and I went to check how many kills I had got and it had said only twenty and so I was really confused as I was playing multiplayer. I went into another game and I saw I was on the leaderboard with 14 kills and 11 shared vanquishes. I then went to check the difference in the total and it appeared that I had only got 3 kills.

I am quite annoyed as I played a long time for the challenge and obviously only getting 2 or 3 kills a game out of 300, it would take a while to complete the challenge.
