Cafe PUBLIC Subset issue

[donap]

HI.
I have a Super User who created a few Public Subsets in Cafe.
When other users open their Cafe link -- they cannot see the NEW Public subsets.

I checked in Architect, and the subsets are DEFINITELY already showing as Published/ Public (The option to publish is greyed out).

How do I allow users to see subsets other users have published as Public ??
Thank you
