The segments of my matomo cloud are not displayed in the segment list

Hello,
I have created many segments for different sites tracked in a Matomo Cloud.
These segments work fine in Matomo, but are not listed each time a data source is created with the connector.
It only appears in the segment drop-down list “by default” and the name of a segment that doesn’t exist in any site and segment I’ve created!
I’ve activated the function for modifying the “segment” parameter in Looker reports, but here too if I go through this channel I always desperately list “default” and the segment unknown to the pack.
Do you have any idea what’s causing this problem?
Kind regards
