Top three things to fix
Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree.
Some stops sit far from the route line, going by the feed's own distance values. Trip planners may draw the route down the wrong path or point riders to the wrong boarding location.
Effort: Usually an export-tool fix, not hand editing.
Turn on 'remove unused shapes' (or the like) in your export tool.
The feed contains route shapes no trip uses. Harmless to riders, but it bloats the feed and suggests stale export data.
Effort: One setting.
Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras.
Some files contain columns that are not part of the GTFS spec. Harmless to riders, but apps ignore these columns and they can hide typos in real column names.
Effort: A quick look at the flagged files.
