IGN Geodesic: bad reference extraction?

[Bibi56]

According to https://geodesie.ign.fr/fiches/index.php?module=e&action=visugeod, 29293A (in Trégunc) is a valid reference point.

Osmose wants to add it in the database as such: https://www.openstreetmap.org/changeset/119037666, so not as 29293A (as it exists in the OSM database) but as 29293A -

The refs are not matching : 29293A - != 29293A

I does not look at this for years. Not sure how - is mandatory.
