New Mail notification sounds when email is deleted from junk folder

This has been a long term problem with Windows Live Mail 

The new mail sound notification works as expected for new mail arriving in my inboxes BUT whenever I delete an email from my JUNK mail folder a few seconds later I get the New mail notification sound.

The visual indicator in the taks bar also suggests a new email has arrived but this  is not correct. There are no new or unopened emails in Hotmail or any other other accounts I use in WLM. The new mail notification is not accurate as presently it is constantly giving false alarms.

Please advise.
