Battlegrounds issue

Hey all, i don´t know since how long this is going i just noticed it today. When i get a match in BG´s i get the opponents deck and can bann 3 champs and that works fine. I bann 3 and go to the next screen but here comes the problem, when i get to the picking screen i have a champ already picked. 3 matches in a row 2 times i had to pick first and had once Dr Doom (R3) & once Hercules (R3) picked wich is what id probably do anyway and one match it picked my Mephisto (R1) and Black Widow Deadly Origin (R2) wich are 2 of my 5 weakest in Deck where id definetly go with someone else or reroll the picks. I wonder if its just me for some strange reason ( using an Huawei 8i) or if other players have the same.
