Contracts that we have deleted are still showing in Reports

(Test) Contracts that we have deleted are still showing in the ServiceDesk Reports > Contracts > Contracts by Status, Contracts by Vendor and Expired Contracts.  They don't show on the main 'Contracts' tab anywhere as they were deleted.   We want to get rid of them permanently as they keep showing up in reports, please advise.
