Welcome Ber!
I am not an expert either but I dabble with OpenStreetMap.org and have modified it often. I think that you are just waiting for CityStrides to ingest the new data from OSM.
I don’t see those nodes in OSM and when I view that city from CS, the last update was a month ago on 2025-12-03
So the next time that CS updates Brookville they should clear up. That is the good news but unfortunately the system has been slow on these updates so you may be waiting a few months.
