Moving an object disappears during drag?

Draw Windows 8.1 and 7 computers When a drawing in a pdf file is opened in Draw and object moved by dragging to a new position disappears during the move and the xy coordinates to not change in be box below. If an object is created in Draw like a rectangle and moved it does not disappear during the move. JERRY

If you boot Libreoffice in Safe Mode (main menu > Help > Boot in Safe Mode) then open draw and try to do the same thing, does the problem persist?
