YLXD50YL losing its colors.

I have 5 YLXD50YL and 2 of them lost the RED and BLUE colors. Red is orange/pink and blue is light purple.
Is to hardware or software issue?
They are both on the latest Singapore firmware. I do not want to update to the version 25 as it breaks the LAN mode.
Also my lights won’t totally turn off: there is a dim glow always on.

I’m on the Singapore server, firmware 2.0.6__0016.

I also have a Color Bulb (color2) which stopped making red.

Any help? Should I ask for an exchange?
