Unable to resize embedded graphics in OpenOffice

The document WNIOSEK O WPIS DO KRS has a CORS logo as an embedded graphic in row 2. The document opens in OpenOffice Writer but the logo is visible at the natural size only; as soon as I enlarge/reduce the picture, either by changing the view resolution or resizing the picture, it just disappears. It happens both in Edit mode and in Print Preview.
I tried to export the graphic to a separate image but it did not work. There is a command Save graphics in the context-sensitive menu; it is undocumented either in the Customisation dialogue box or in the on-line help. I used that command and the resulting image was blank. Copy/paste to GIMP via the X Clipboard gives the same blank result.

Update: the problem goes away after converting the document to OpenOffice format.
