Need to copy value in one field to another when a status field changes all within the same record

Import Style:
-Merge in Ops, [Op ID#] = [Op ID#]

Import ops that meet the following criteria - Show ops where:
-all of these conditions are true
-[Related Project ID#] is equal to the value in the field [Related Project ID# of Focus Project]


Yes, the child records have the correct [Related Project ID#]

If I manually click the Import button, I get a green box pop-up that says "A total of 139 Ops were read in.139 existing Ops were left unchanged."
