Registration Pains

I keep being told that I have greater than 50 credit hours towards my registration date at Gaston College, but every time I try to enter the system, I am always given a different date than quoted for registration. Its a weird little bug in the way that Gaston counts their hours. What I keep getting told each semester when the system makes me wait an extra day (or a year ago, 2 days), is that it is based on the number of hours completed at Gaston. No where is this mentioned, not in the catalog, register, or in the table below captured from the registration system itself. I have > 50 credit hours, but I have <50 and >25 completed at Gaston. This sucks.
