Mass delete contact by report - error

Hi Sugar Club, 

I would like to mass delete contacts from a distribution list in Market, using the Mass delete contact by report functionality (from the Admin dashboard).

However, even if the operation is completed, no contact is removed from either the report or the distribution list.

I receive an automatic email with this error 'ContactId does not exist in report', despite the fact that I have checked several times that the ID actually exists in the report.

What am I doing wrong? How can I achieve the mass delete contacts goal?

Thank you very much in advance.

Kind regards,
