Please, help, red colors not working

Hello. First, I apologize for my extremely weak English. i’m quite desperate already. I have a Yeelight led strip and after the firmware update, I noticed that the red colors are overshadowed by green so that almost all colors are yellow or light green. the only color that can look good is blue. and disconnecting directly to the power source I can see that the red LEDs work but when in normal operation, it is not possible to see because they were overshadowed. I urgently need a firmware downgrade or an update (not available). anything that corrects this problem.
