Logged out message on categories pages

I don’t know whether this is a UM question or a Woocommerce question really since I’m using both together. Anyway, when I set Content Restriction Mode under Memberships to Hide content only in Woocommerce Membership settings, it works. BUT yesterday, the notice “This post is only available…” also appeared on the list of posts on the categories pages. I must have turned this function off but, for the life of me, I don’t know how. Help is greatly appreciated.
