Gauntlet match completion inaccurate when player is promoted to another squad

I had the weekly challenge "Complete matches in Gauntlet."

In one match my squad failed to qualify, but I was promoted to another squad that did qualify at the end of the round to replace a player that left mid-match.

This new squad failed to qualify the next round and that was match over.

The bug is that this counted as completing two matches for the challenge when really it was only one. It also counts as two losses, when it should really only be one.
