BuddyPress.org

Old thread, but here’s a possible fix that worked for me.

The hidden groups in the Groups list have the class “hidden” applied which is a fairly common CSS pattern for hiding content. I added a CSS override as a workaround.

#groups-list .hidden {
    display: list-item !important;
    visibility: visible;
}

Really, in this case, I think BP should use a more specific class name. Something like “hidden-group” would resolve the issue.
