After you have inserted the cross-reference, add a so-called numeric picture switch to specify a number format.

Press Alt+F9 again to hide the codes, and press F9 to update fields in the selection.
Alternatively, manually add a bookmark around the figure number and then insert a cross-reference to the bookmark text.
