[OSM-talk] Rendered boundary not present in data

[Markus]

Hello,

I've come across a boundary rendered on both OSM Carto and the
Humanitarian layer that isn't present in the OSM data:

https://www.openstreetmap.org/?mlat=47.50350&mlon=-3.13473#map=19/47.50350/-3.13473&layers=D

The correct boundary, which is present in the data, is also rendered:

https://www.openstreetmap.org/way/38707921

(Note that the incorrect boundary was already rendered before my
recent edit to the correct one.)

Any idea where that ghost boundary might come from?

Thanks in advance for your help.

Regards

Markus

PS: I hope that this is the right mailing list for this kind of problem.
