Chart in Calc corrupted when copied into Impress

I am trying to put together a presentation and put in various charts I have created in Calc using copy and paste. I have two pie charts which works fine. However the bar chart gets corrupted.

Chart in Impress

Am I doing something wrong (most probable) or is it a bug?

Many thanks,

Allan

If you paste the chart into Impress (Paste Special) as GDI - does the problem exist any more?
