Copied Field doesn't have the same usage as the original

I created a check box field and it's currently used in 7 forms/reports. When I copied it to add in another area of the same form it shows as only being used in 2 forms/reports. How can I add it to the additional areas I need it in? I want the copies to function the same as the original. I attached screen shots of the original and the copy. 

Thank you!!
