I have entered my RRSP slip information. The total amount should be $8000 but the Review screen, under RRSP/PRPP summary, shows $10,600. Why is the amount incorrect?

I have tried importing my CRA slip information again and have manually entered slip information, but the discrepancy persists. I also tried logging out and logging in. Is there an additional amount that is added to the $8000 somewhere and i'm missing it?
