Access Control

I am trying to restrict access to some Spaces using FCRM tags. I use LifterLMS as my Membership control. When a person joins via LifterLMS, they are tagged with "member"

I want to restrict access to some groups to ONLY those who are tagged "member"

I have my Portal set to "Logged in Users only"

In testing, the tags are ignored and any logged in member can see and join the Spaces - I have checked the FCRM access control and set the Spaces to the relevant tag but still not working...

Am I doing something wrong or is it a bug?
