Is there something wrong with my RX100? Having "purple" issues on left side

Hi

I'm an amateur and just bought the RX100 and as a previous Canon S100 owner I noticed a purple color all over the left side of my pictures. Is there something wrong with my camera or did I something wrong?

On the first image the sun was on the right side, with the other two images the sunshine came from the left side on my back.

I shot in RAW format with auto white balance.

Thanks for any hints because I'm just not used to such a behavior with my Canon S100 and EOS DSLR.
