Hi Hannah, in the future please don't delete ways without first understanding the relations that they are in. Some of the sections of trail that you're deleting then re-creating are part of bigger relations, and you're not adding them back in. Eg The East Link Trail is a group of paths (ways) which make up one long trail which is called a relation in OSM. I'm fixing the ones I find but can you please look up how to do it correctly oherwise some of your change sets may need to be reversed. Thank you.
