Parts of this path (such as https://www.openstreetmap.org/way/93075646) are tagged as designation=permissive_footpath, so foot=permissive is the appropriate access tagging — why have you changed it to foot=yes? If the path is indeed a permissive footpath, it should definitely be foot=permissive (and probably also bicycle=permissive if bicycles are allowed at all).
