The contracts not being counted into the total are MMA1 contracts. MMA1 documents are used for master agreements where a prime vendor pool has been created. MMA1 agreements are parent contracts to CTA 1 and are used only for reference purposes; therefore, since the children to the parent are also listed, including the MMA1's in the total count would be double-counting. When exporting all contracts, you will see the MMA1 contracts listed. It is important to remove these when adding up contract value amounts.
