Cue/loop (In/Out markers)

Hi

Using Sc2900x2 (Dn-x1600) with engine 1.5

I’ve pressed the in and out button (next to reloop) on a track in engine. And I can clear the out marker (thus removing a loop). But the in marker stays on the track, with-in engine and the players. Is there a way to remove the in marker?

Using engine linked with players over ethernet?
