1463 Strike Mission not following flightplan altitude if altitude in AGL

Please see attached.
At the end of the planned hold, Tater flight does not follow its flightplan altitude and instead drops to min altitude- all the way to the target. In comparison, Farmer flight does much better at following its flightplan altitude (36000 ft to WP 4).
The only difference between the flightplans is that Farmer specifies all WP altitudes ASL, but Tater flight uses AGL (i.e. Terrain Following checked) from WP 4 to 6.
Terrain Following != Minimum altitude
Also, I think both flights need to have their speeds checked. Both should be unlocked in time and speed and have cruise specified, but the WP 3 to 4 leg seems to be undertaken at 'loiter' and WP 4 to 5 at 'full', etc.
