Your first warning status appears to be an error, at least according to the info you posted and the SAP policy. Your CUMULATIVE gpa did not drop below 2.0; therefore, you were not in violation of the SAP policy for gpa, which states that your cum gpa must be above 2.0. If this is correct, you should not have been placed on warning status that term.
If you should not have been placed on warning for summer, then you would have received your first warning status at the end of fall semester (meaning you would be on warning now rather than actually losing aid for the current term). You would not be subject to automatic disqualification without warning, because it is mathematically possible for you to achieve the 67% requirement by the end of the current term (21 earned + 12 possible = 33; 34 attempted + 12 fall = 46; 33/46=71.7%) .. and because your gpa is currently 2.0, it is mathematically possible that you will have a cumulative gpa of at least 2.0 at the end of the current term.
If you have remedial classes, it is possible that those are skewing things ... they may not count & thus will throw things off. You might actually have been ineligible if any of your earned credits were remedial classes.
I would sit down with an aid advisor and ask to be shown exactly what happened, when, and why ... and at each step, ask to see what part of the SAP policy it violated. Best of luck to you.
