Struggling on the GMAT DI insanely!

In my recent mocks I have consistently scored over 84 in both Verbal and Quant but I keep getting worse in DI for some reason despite doing well on the DI questions on GMAT club.

My latest DI score was 63 (6th percentile 😭😭). How is that even possible?

I have just 10 days left before my GMAT test and I can't figure this section out.

Please help!!
