In v4.255 the flight path does not show below zoom factor 11

I've not flown for a month so started Plan-G and up came the update message, so I got 255 but comparing with .246 (my previous version) the flight path no longer shows when zoomed in below 11, I use this to accurately measure flight path distance, in 246 it still shows all the way down to 17

Well this is embarrassing, it's working today! only my second try with .255
