Unable to add survey to dashboard

Hi all,
We have a peculiar case of invisible surveys. A user in my company cannot add surveys as sources to the dashboard. When she tries to do so, she sees only several surveys as available to be added, only about 1/3 of all the surveys she owes. She has been buiding dashboards before with no problems.
We tried to add the surveys as data sources in the dashboard tab, and then try to add them via Dashboard settings, no luck. She shared the surveys with me, and even as a Brand Admin I have the same issue. We have created a support ticket, but i wonder if anyone has had same problems lately..
