Am I being dumb.. but can't seem to hide spaces? All viewers can see all spaces?

We have different clients (customers) accessing Jira where we can plan/track projects and support etc. We want to have Confluence Spaces for documents.  However, we don't want clients to see each others spaces...  We can turn off access by restricting the spaces, but it still show them under 'All Spaces'.  How do we do this?

No, not dumb at all. This has been my experience as well. I don't know of a way to hide these on the All Spaces view. 😞
