Content (please ensure you mask any confidential information):

Hi,

I see the rate display value has three options , while i dint want the calculation to be show either as primary or secondary, but want to show the rate.

I dont see an option to select blank, how can we make sure only the rate will be showed but the primary or secondary isnt.

For eg: i dont want the primary part to be visible, however i want the value 3126 annually to appear , but not the value 260 primary
