Hello Moinsdix,
You added "F25" to new cycleways that make part of the new cycle highway F25. However, these cycle paths don't have a name. They are linked to each other via a cycle route relation > https://www.openstreetmap.org/relation/19127685
I will remove the names on the ways.
Please take this into consideration with future edits. Thanks and all the best with further mapping!
