I have 1 profile with 2 build plates.

First: Do you need Schrader or Presta Valve Caps:

Schrader is for cars/trucks/motorcycles/Kids Bicycles/Department Store bicycles. (fat valve)

Presta is for mid-level and higher bicycles. Mountain and road. (skinny valve)

Finally: There are 2 plates in the profile. First one is SCHRADER and the second one is PRESTA.
