Top three things to fix

Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar.
The feed has a stretch of two weeks or more with no service running. A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.
Effort: A review of your calendar dates.
