Odd Behavior After Draft Pick When You Have More Champions Than Fit On Your Bench

A few times after shared draft I have had more champions that can fit on my bench. If I sell one on my bench to make room for the one I picked up in the Draft Pick, it will swap one of my active champions to the bench and place the champion from draft pick onto a hex.

The champion from Draft Pick that exceeds the bench limit should move on to the bench when I sell a champion, not a random one of my active champions.

Thanks.
