Can't set waypoints with ch 7

I can set waypoints in mission planner but I cannot set waypoints with the ch 7 switch.
WHY?

i assume that you have ch7 settings to “record waypoint” instead of “record cruise speed” isn’t it?
I am not sure, but since few weeks i cannot setup the “learning mode” anymore in the previous stable release, where the ch7 worked fine, i am going back to the beta this week, and I will bring here my feedback about this issue.
