Will Fortimanager fail or skip variables if there are duplicates in the provisioning template?

Hello Everyone, 

 I have a production device that has already had our template that is for 1 MPLS -1 internet connection ran on it. I want to add another internet connection to that device. I already have a template for 1 MPLS- 2 internet connections which would be perfect. Would I be able to just add the variables for the 2nd internet connection and run the 1 MPLS-2 internet template even though it will have all the same variables from when I used the 1 MPLS- 1 internet except for the additional 2nd internet connection, or will it fail since there will essentially be duplicate variables? I thought I remember hearing or reading somewhere that it will just skip them, but maybe I made that up. 

Thanks!
