RPM DROP

DCT. I had this issue twice, so the issue is when i brake after i accelerate, rpm begins to drop about near idle rpm. any ideas why it happens?

When I brake harder than normal in auto mode, it would actually rev match like I'm in manual mode when shifting down from 3rd to 2nd, or 2nd to 1st, not so sure. But I guess it's the nature of DCT?

DCT acts weird sometimes. Almost every time I make a right-hand turn into my bank parking lot it rev matches twice. Once when I downshift to first before making the turn (normal operation), then again while in the middle of the turn (with me in 1st gear not downshifting or touching anything). Never happens in any other situation.
