If your user see some elements with "default name" names like this for example that means that some connections in MI database are broken. In order to fix it you should:

1. Connect to machine where MI is installed via ssh or open terminal on this machine.

2. Enter MI mysql database. Usually you should enter: 

mysql dahsboard

and then enter:

call element_dashboard_name_rebuild(null, null, null, null, null);

Your issue should be fixed, please verify that in the browser.
