Track windows are large

i notice when i drag a loop in the sequencer the track size is very large. it covers the whole sequencer. i re adjust it to a more manageable size and save and close the project, when i reopen it the audio parts are huge again! what am i doing wrong? thank you in advance.

Can you post some screenshot that show the issue? If you’re on iOS or Android make sure that the track is not maximized with the magnifying glass on the track’s top left corner.
