Characters without %, class indication or boss kill association

https://www.warcraftlogs.com/reports/6MrkCdP7bZB3F9wx#fight=2&type=damage-done

If you look at those logs everything seems to be working properly except for 3 players

Akroma is a warlock, the log recognizes it and has everything right except his parse % which I don’t know the reason for.

The other 2 players, Hurlisa and Shärwÿn have no parse % and the logs/site seems not even to recognize their class and spec.

In both cases when accessing their profile there’s no boss kill matched to them, so even though they killed 6 bosses it still shows as if they killed none.

Does anyone have any idea why this happens and a way to either fix it or prevent it from happening again?

Thanks in advance
