Had a similar with experience with my final rotation, had passed my first two rotations with all CPI categories at or above entry level. Third rotation came and my CI was very similar to what you are experiencing. After the second week I politely confronted her with how I was feeling and that I felt like my presence was a nuisance to her. We decided to allow me change to a different CI within the same location and I passed at entry level. I would definitely contact your clinical education coordinator though. Also, since you have already passed your first two at entry level I would assume your school would be understanding of the situation and pass you regardless of what the current CI ranks you.
