Cannot find Address 1: Shipping Method field for Accounts Entity in MS Flow

[Ajita]

Hi

I am creating a Microsoft Flow for creating new records for 'Accounts' entity. However, I cannot find the 'Address 1: Shipping Method' attribute for Accounts in the list of attributes appearing when Accounts entity is selected.

All other attributes are appearing but not this one. Please refer to screenshot:https://www.screencast.com/t/KhiIdyRXlEQ5

Is there some setting which I am missing. 

I also tried to use field "Shipping Method" for same(to insert Fedex(code:3)). Please see screenshot:

But it returned error: https://www.screencast.com/t/Nz9rmyb6UlK
