Receiving duplicate emails for some watch list matches

Hi.  For many months now, I've been receiving two emails for some watch list matches.  I thought that eBay might be aware of the issue and resolve it, but maybe no-one else has mentioned it.

 

It only seems to happen with newly added watch list entries - I'm pretty sure it doesn't occur with my older watch list entries.

 

If I turn off email for the watch list entry, both emails stop.  If I delete the watch and then add it again, I get the duplicate emails again.

 

Can anyone offer any suggestions?

 

Thanks,

Peter
