Hi,
TMA gets new bearings every 2 minutes. With right mouse button click on the windows you can choose the time window you can display.

Yellow lines are (by the book) the active sonar intercept. Maybe they get moved outside the displayed time window if it is too short to display them.
Or simply the other platform stopped using active sonar for some time.
