RSS Feeds - duplicate feed entries

Is anyone else having problems with RSS Feeds where a particular feed entry gets sent every time the feed refreshes, so you get duplicate entries?

I have it with a number of feeds. Deleting and recreating the feed does not resolve the problem. One feed I get it with is the IBM developerWorks articles (IBM Developer). Every time the feed refreshes I get duplicate entries for the articles ‘Achieving ultimate storage and server cost savings with DAOS…’, ‘Automatically deploy software with a simple framework based on STAF and Lotus Notes’ and ‘My developerWorks: 6 ways to build your technical skills and your professional network’. Looking at the XML produced by the feed I can’t see any reason why thy are being sent several times. Most feeds are working fine, but a couple are producing these symptoms.
