All strat objects, cities, factories, and HQ's, should be associated with a country, not a field.
Select all the objects at that facility, and bring up the object properties box.
Then where it says "owned by" Field #, click once on the button that says "Field" and it will change to "Country".
Then enter country 1, 2, or 3, as appropriate.
