All business rules not firing if Quick Create used

I have an entity where Quick Create is enabled and it has the following Business Rules:

1.  Business Rule: Calculate Gross Fees

• If Units contains data
• And Unit Cost contains data
• Set Gross Fees to Units * Unit Cost

2.  Business Rule: Calculate Net Fees

• If Gross Fees is > 0
• Set Net Total Fees to Gross Fees + Client Fees

 The Units, Unit Cost, and Client Fees are entered on the Quick Create form.  On saving the form, I can see that Business Rule has run and the values are correct; however, Business Rule 2 does not run -- the values are not appearing in the sub-grid View.  However, if I click on the item from the sub-grid and open the default form, the values are there.  Going back to the sub-grid View the values then show up.  Why am I having to click the item and open the default form to get it to run the 2nd business rule?
