Brian,
If you erroneously enter the wrong information for the insurance, you will have to clear all of the entries that is incorrect to get rid of the choices of insurance.
It would make sense to have one insurance linked to address and phone number, etc. so that once the data is entered correctly, there is less chances for making new errors.
And I see you found the "common code" box. It's a nice square box that you can check (it'll keep you occupied) and uncheck.
The "common code" box does nothing. It remains checked but does not prioritize or have any other function. It's tempting for me to say that this is the magic button (but that would be too cruel a joke to pull). I know! Like an idiot, I went through the list and checked the boxes to my heart's delight (when I should have been charting)... to find out the common code box is a box and only a box.
