1:1/1:Many Relational Issue

Hello - 
I am creating a simple inventory tracking app. I have two forms: 1)  Form A, which shows Form B and a Quantity count, 2) Form B, which contains Manufacturer and Product Name.  

On Form A, I used lookup fields for the two fields on Form B.
On Form A, when I click Manufacturer and "Add New", I get a full display of Form B, versus the single field I selected when creating the lookup field.

Any idea why this is happening? (I am very new to Creator so I'm starting simple)

Thanks for any help,
