When you go to Configuration, Profiles, full-ha, messaging, clustering there are not shown elements in table (in all sub tabs). You can see elements in CLI (there are some defaults). When you add some new broadcast-group for example through CLI still any of groups is shown in Web console.
If you add group in web console, after adding, all groups are shown in table in web console.
This problem is in all sub tabs of messaging clustering(broadcast, discovery, connections).
