IMHO, to avoid future complications, I'd recommend reverting changes and re-surveying them again manually. With the right app, this is a nice evening walk :) I do this frequently myself.

You can also start a new topic in our community (forum) to discuss this further: https://community.openstreetmap.org/c/communities/il/50
