I believe the reason for the blanks is that you are looking at the department (i.e., Finance) rather than each of the specific employees. As you can see, all that data is date or booleans do not likely have a summary in the blueprint or cannot be summarised.
Ok, now I get you. Have you checked that your Bonus % is different from 0? It looks like you salary is there, but it may have been multiplied by a number that is 0. Alternatively, the lookup could have worked, but the line items that you used for the lookup could be blank and you need to populate them.
