Norton Save and Restore 2.0 Invalid Backup History

Hi,

 

I am currently having issues with the Backup History tab in the Advanced (I think, maybe Tasks) section of the product.

 

I have 3 backups listed, however, each has a small white question mark in a blue circle against it and I am not able to delete or clean these up.

 

I am supecting that these backups are not valid and I would like to remove them.. If I right-click on any of them and choose "Restore Files" no files are listed.

 

Please can someone tell me how to remove these entries?

 

Thank you
