Incorrect card displayed!?

I had 2 Volibears on 'the bench'.
The round ends and there is a Volibear available

clicked once... nothing. click twice... nothing. repeatedly click... nothing

Sat there questioning myself I try move some champs to the field but I have 6 champs on the field at lvl6. [sg-lux-2] now thinking this is a BUG I sell one of my champs (that i didn't really want to)... Click Volibear

LEONA appears on my bench!? [sg-shisa]

No level3 Voli for me... I lost LP. [slayer-pantheon-thumbs]
