Max number of boundaries = 6 + outer? (v4.1.12)

Good afternoon.
I’ve finally installed my GPS rover on the tractor yesterday and went into a paddock today. That paddock has got quite a lot of trees in it, so I created for every free standing or group of trees an inner boundary. I was only able to create 6 inner boundaries plus the outer one, as I can’t scroll down to ‘create new’.
I actually just tried that on my desktop with the wheel of my mouse and again, there’s no scrolling.

Is there a way to scroll at all?

Cheers from Australia.

Hi - I was having a similar issue - did you find a solution to this ? Thanks
