Bookmark is dragging when clicked once

Hi everyone!
I have just upgraded my 16.04 Ubuntu to 18.04.1 Ubuntu.
I have added bookmarks in the left panel of my Nautilus that I frequently use for my work, but when I left-click once on any of them the bookmark is dragging together with the mouse cursor that is changed to a "hand" with "+".
Destination of the bookmark is also opening.
But I have to click ESC on the keyboard to get rid of the dragging feature OR I have to click again on the left panel to return the bookmark on its place.
It is quite annoying...
Thank you for any help!
