Can't select the new 1000 win hero portrait

When I click the make favorite button it doesn’t do anything. I am able to switch to other already existing portraits, like Sir-Annoy-O, but not the new 1000 wins one. If I link the portrait to a specific deck it seems to select it but when I press play it’s reverted again to the old portrait.
Blizz pls fix this! I’m looking forward to playing with Lightforged Uther. Meanwhile, I’ll be spamming players with Sir-Annoy-O. hello. hello. HELLO. Hellllllooooooo. If this is not fixxed soon you’ll lose customers for sure :wink:
