Notice the word "states", "North Carolina", and "Rhode Island, and Providence plantations". It looks, from the terminology, like they were called states before they ratified the Constitution.
Regardless they were differences between the northern "wahtevers" and the southern "whatevers". The differences got worse and led to the ACW. But they existed during the Constitutional Convention.
Sounds like you ought to take your complaint up with the states involved since it was their decision, not mine, on when they placed the dates they achieved Statehood.
