3814131 - Why is there "No Vendor Supplied" in the Vendor Description field when it should be the vendor name?

When we move our Taxi expenses from Available Expense to an Expense Report it is populating the Vendor Description field with "No Vendor Supplied" instead of the correct vendor. As this is a required field it is also triggering a red exception message "Missing required field. Vendor Description." and where our user can not modify the field, they are unable to enter the correct vendor to submit their expense. What can they do to resolve this issue and submit the expense?
