Copter Rally Point Altitude Type

hello @rmackay9

i was doing Copter RTL on Rally Point with RTL_ALT_TYPE =1 (Terrain).
But it seems Rally point only considering the ALT type to Relative not Terrain.
Actually my waypoints are in terrain alt type including RTL command in the Mission.
auto mode RTL doing consider terrain alt type but Why Not in Rally Point it only consider relative type.
