Auto mode DO_SET_REVERSE dumb error?

Finally making huge progress on my skid-steer tank. I got Quiktune to work, RTK GPS on fixed and all is well. Marked some waypoints and set up auto. Follows quite well. However, I added some ancillary commands. Where it says “waypoint”, I pulled down reverse. Also tried changing speed. It ignores these commands. I have pulled it into a garage, so want it to reverse out of the garage. So first command in the string was “DO_SET_REVERSE”. I also had second command “DO_SET_SPEED”, followed by waypoints. Later, after a few waypoints, added a “DELAY” and “RETURN_TO_LAUNCH”. When I started the waypoints, it immediately did a full 180 pivot inside the garage and headed to the first waypoint at cruise speed, ignoring the reverse and speed commands. Later, it also ignored the delay and RTL commands. I assume I’m making some simple cockpit error that keeps these commands from being enabled. Any advice?
