I know if you place down a seek-and-destroy waypoint the unit/group will do a search pattern from the waypoint placement for a few minutes and then it would stay idled. Until a new contact with Enemy units occurred then it's set behavior combat mode will kick in. If you add a cycle waypoint it should theoretically set that unit/group into a continuous loop with the seek and destroy waypoint however this does not occur. The seek and destroy waypoint will end and disappear from the map. If you go into Zeus or MCC interface you will see the waypoints get deleted. If you use a move waypoint and a cycle the waypointe stay on the map and the unit/group would be put into a continuous loop following the waypoints place down on the map.   I don't remember the waypoint being like this. Did something change with some game updates. Are there any solutions to have a seek-and-destroy cycle waypoint continuously work on a map?
