This is by design. The single Glance endpoint visible in UI can be used to make direct API calls for that endpoint. Similarly, the other Glance endpoints listed by the below command can be used to make the API call for the respective Glance nodes.
# openstack endpoint list --service glance
The Nova and Cinder services use Glance clustering. This ensures that the best possible endpoint is chosen by the service during runtime. You can get the list of currently available Glance cluster endpoints by running the below command.
# openstack endpoint list --service glance-cluster
