Community College removed Pell Grants

My fiancé is starting nursing school this semester and she had already taken the other classes that would have been taken during this semester so she only has 1 class which is 6 hours registered. The FA office told her that she lost her Pell Grant since she is not full-time. Her GPA is 3.88 and everything we have been able to find is that the Pell Grant would be lowered if going to half-time, not taken completely away. When she added 2 other classes to make 12 hours, they told her that she still wouldn't get the Pell Grant because those classes don't count towards her degree program.

Any advice or insight would be greatly appreciated. TIA
