S1 Color problems with Home kit after update

After updating my Yeelights S1 Color my Home App lost the hability to set the right colors. Every time I try to set my lamps full bright and white they turn kind of blue/green and the brightness is really low.

Before the update they could fill the entire room with light and make it really white. I wish to downgrade but I expect Yeelight team to fiz that as soon as possible.
