Event Virals don't count towards the "Undefeted Champion" weekly

The event Virals, the ones that spawn after basically every fight, don't counts towards the "Undefeted Champion" weekly.

I've found killing virals that are walking around on their own counts for this but not virals that appear due to the event. Have you tried turning the event off?

I did with the one you have when starting a chase it work perfectly

The chase Virals are not the event virals. The event virals are the ones that spawn when you make sound from combat.
