Michael Kors Savannah Large Satchel

I have only worn this bag maybe 3 times. It got stained on the bottom during a move (pics attached). I think it’s a bleach stain but I honestly am not entirely sure. It’s on the bottom of the bag and wraps around the front right corner slightly. Also a very small dot stain on the inside of the bag near the magnetic closure, also picture. Lovely bag, I just never fancied a purse this large.
