There is something wrong with the rendering of the color of pieces : In https://chessdream.ai/?dreamId=ab86d6a2-470a-4238-9181-8b4d3... there are two white kings, and queens. The position is correct though when viewed on Noctie.

Edit : In fact, the kings and queen are neither black or white but a third color : grey

Edit 2: There is probably some issue with the adjust piece count, when opening the same dreamId in multiple windows. As following the same link doesn't have the same number of pieces.
