Unable to add Contract details for contingent workers

Content (required):

Hello,

We are trying to add contract details for contingent workers that got missed during initial HDL load. However, it is not allowing us to do so. We can definitely edit the contract details for those whose contract details have been added but cannot add fresh. How can we add the contract details for already existing contingent workers. The employment model attached to the LE is Two Tier Single Contract Single Assignment

Thanks
