Duplicate Advertisements are getting created

Hi,

I found one strange problem in my SCCM 2007 R3 Environment.  I have lot of advertisements in my central server and if i do a double click on any of the advertisement, it is creating a duplicate advertisemet with the same name but with a new advertisement ID. 

We are creating advertisements in diferent folders under root, based on the application category but the duplicate ones are getting created under root.

Can anyone suggest some possible causes for this issue?

Thanks in Advance

Regards
