Make Single Number Reach Checkbox respect

Make Single Number Reach Checkbox respect "answer confirmation" current state

When you click the tick box next to a number in the single number reach section in the "Call Settings" quick menu at the bottom left of the window, it automatically defaults to disabling "Answer Confirmation" for that number.

If you were using Answer Confirmation you must go into Settings -> Calling -> Scroll down to the numbers section and edit the existing number to re-enable Answer Confirmation. Or enable the location from here as enabling the location from the edit screen will honour the current state instead of changing it to off.
