Waypoint Radius display in Mission Planner using Altitude Uints setting

[FirebarSim]

Issue details

In the Mission Planner "PLAN" with Config>Planner>Dist Units == Meters and Config>Planner>Alt Units == Feet the display of Waypoint Radius is shown as the value of the WP Radius field (in this case 90) but using the Alt Units.

With no other changes than setting Alt Units to Meters the Radius display will correct itself.

Values appear to save in meters (judging from my poor confused aircraft's behaviour).
