Hi Chris, can I ask where Strava is rendering this please? If it is the heat-map, then deleting these will not impact on the heat map. If it is in the Route-Planner, this is updated monthly and so will still be present until perhaps March. I would suggest that tagging these appropriately is far far better than continually deleting these as they pop up. Can I ask if you have contacted the creator of these tracks on OSM and come to a sensible middle ground.
