Only Run Flow When Conditions are met

Hi, I have a flow that runs when a SharePoint item is modified or created. It would take the DisplayName from a People/Group column (Employee Name) and add it to another column (First_Last_Name). This is working right now. See below

I have another People/Group column (Specify Acting) that I want to get the DisplayName and copy it to another column (First_Last_Name_Acting) but only get triggered when "Specify Acting" is populated. Specify Acting only shows up when a specific choice is selected.

For this one, it would concatenate the word "Acting" and the DisplayName then copy that to "First_Last_Name_Acting" column.

I tried copying the same condition from above changing it to the columns that I want updated, then adding it after "Update First Last Name" but it keeps triggering even when "Specify Acting" is not populated. Not really sure where in the flow should I add this step.
