Cannot change pin position

I’m not sure if this has been brought up before, but I just realised that I can’t change the pin position of the index cards from center to right in my copy of beta 2.
When I go to preferences and select “rightâ€

Yeah, this was a weird bug that popped up between beta 1 and beta 2. Somehow the checkbox that does this in Preferences lost its connection to the actual setting - no doubt whilst I was messing around changing the Preferences panel. Anyway, it’s fixed for beta 3.
