When you, a Responsible Organization (Resp Org) user, logs into the TFNRegistry, the Controlling (current, old) Resp Org and Acting As will be the same. In this scenario, all the Template related functions on the Template Record Selection (TEC) page will have the same Controlling and Acting As Resp Org. This is the existing behavior of the TFNRegistry without changing the Acting As.
To change the Acting As, please refer to Select a New Acting As for more instructions on how to select a new Acting As Resp Org ID.
