Strip can’t display the whole color spectrum anymore

Hi, I have two strip lights. I have had them for less than a year, and they worked great. But for the last week, one of them hasn’t displayed the correct color anymore. I went to play in the settings, and when I try to change colors, it seems to be limited to green and blue mainly, the colors in the middle of the spectrum in the app. It doesn’t seem to be able to display the colors on the outside anymore: red, orange, yellow, pink. Note that the other strip still works great. I have unplugged and replugged the lights, but that didn’t fix the bug. Help?
