as I have previously mentioned, these are bike and foot paths, that means that they have tags of "bicycle=designated" + "foot=designated" + "highway=cycleway", so stop changing the bicycle=* value. there is  ageneral access=private, that already tells you that it is private, disgnated tells you that this path si specifically for use by bike and foot with the general access=private telling you its private bikes and pedestrians, please stop changing this.

Happy mapping,
