Explain this to me like I’m 5

So, my lease turn in for my Jeep 4xe is this September. The projected residual value for it at the time of purchase was going to be around 44k at turn in. It’s currently blue booked at 34k for the same year, make and model. The leasing company (ally) said that when they take it to auction and sell it, I’m responsible for whatever needs to be made up.

Is…that right? I’ve leased a truck before and this wasn’t remotely what happened. I could potentially own upwards of 10k-15k on this thing?

EDIT: I’m not turning it in early.
