Hi tmz,

Thanks for your answer. This can happen, but can also be fixed again :-)

Please fix as follows:

1. Open this link referring to the relation:
https://www.openstreetmap.org/relation/4263150

2. Switch to edit mode (you might need to zoom in)

3. Add field, enter "boundary"

4. Set the value to "administrative"

You can check with the link in my first comment of you were successful (may take some minutes).

Thanks for fixing and happy mapping
