Remove DnB Dashlets from the list

We are upgrading our on site Sugar Professional from v9 to v11.0.1 and I found several  dashlets avalable in Accounts whose labels are missing, not only that, but they don't seem to be actually available to be added. We don't have DnB Connector credentials so I would not expect these to show up.

Any thoughts on how to remove them from the view?

Thanks,
