Widget “galleries list” Mediapress not shown in a context

I’m experimenting the widget “galleries list” with a buddypress site & portfolio press theme and find out that the list is not shown when the user is not logged (the list is show when connected) only on a large screen view. If i look on my mobile , the list is shown even not logged.
have you a solution to this issue ?
thanks
