Top three things to fix
Review the rule documentation for 'equal_shape_distance_diff_coordinates' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Equal shape distance diff coordinates (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 buses jumping backwards or mis-order stops.
Effort: Usually an export-tool fix, not hand editing.
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.
