Deleting charts in a profile

 

I have a profile which contains a number of currency charts. I want to permanently remove a couple of the charts from the profile but am not sure how to do so. If I have the profile open, right click on the chart(s) and select "close" they are deleted. I do "save profile as", select the existing profile name and overwrite the profile. When I re-open the profile the deleted charts are still there! Am I missing something out?

Regards
