How to customize toolbar in X7?

Good day! Im using CorelDraw X7 and trying to customize default toolbar. Im clicking on toolbar right mouse button, select Customize -> Standard toolbar -> Properties... The toolbar properties window is appear. I do remember the time when I drag and drop icons AWAY FROM toolbar to delete them and from the list TO toolbar to add them. Now I can do almost nothing.

I cant  catch the button from toolbar to throw it away (but I can right click and select Customize -> Toolbar item -> Delete). And also I cant select and drag the button from the toolbar properties window list to the tollbar. In both case buttons are not draggable. How to customize this toolbars now?
