Top three things to fix
Review the rule documentation for 'trip_distance_exceeds_shape_distance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Trip distance exceeds shape distance (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Re-generate shape distances in your export; flag to your vendor if it persists.
Some trips have stop times whose distances along the route go backwards. Apps can show transit vehicles jumping backwards or mis-order stops.
Effort: Usually an export-tool fix, not hand editing.
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
23036 of 23036 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the transit vehicle itself can take them.
Effort: A default or per-trip field in your export.
