Okay, so I FINALLY registered Madeleine with the AKC. I got her Pedigree today but I'm a tad confused how to read it

From what it looks like to me Madeleine's father is also her maternal grandfather
Am I stupid that I can't decipher this thing?? Ugh, I'm really upset about this.

I don't want my little girl to be inbred
I've learned so much from YT since I got Madeleine and if I knew then what I know now I wouldn't have purchased from this breeder. What type of breeder breeds a male offspring with it's mother?????????
No matter what I love my girl more than anything, but this does upset me.
