Can't add folders to MediaBay

For some reason I’m not able to add folders in the “File Browser” pane in MediaBay. I see “All Media” but no checkbox or anything.

What am I missing?

Nuendo 8.3.x AND 7.1.4

(see attached)


I came across to this issue yesterday for the 1st time. I was able to reproduce it only, when I open MediaBay by using “Search in MediaBay” Key Command (Shift + F5) after the very 1st start of Cubase/Nuendo when I had trash preferences.

How did you come to this state?

Unfortunately the only one solution I found was to trash Cubase/Nuendo preferences. Then start Cubase/Nuendo and open MediaBay via common Key Command (F5) first.
