Hello,
the names of the arranger track events are not shown when the tracks height is 1 row. Marker tracks however show their name, even when displayed at 1 row.
There is a setting in the preferences “Smallest track height to show name”, which seems to be dedicated to midi/audio events only, as there is also a setting to show “data” at 1 row (arranger events obiously don’t contain data), but unfortunately this setting also includes arranger events. Marker tracks are not included as said previously.
