I agree!! It looks to me like you are reaching for your stirrup. I’d have you shorten your stirrups a hole.
That said, that saddle block and flap don’t look right. That looks like the Icon Short Roll - which is meant to support your thigh, not your knee. I also ride in that roll, and my knee sits just below the bottom of the roll. The flap is also 1, maybe 2, sizes too long. The flap should end around the fattest part of your calf. To me, that’s about 2" below that silver dot I see on your boot. But you have maybe 3" more flap below that. It makes it so much harder to get your leg on your horse’s side.
