Missing Red color on lightstrip plus

Hi, suddenly some of my LED from lightstrip plus only can turn green or blue… some red light is not on… when i turn on the yellow light color, it turn green for some spot…

Please make confirm if connector is well.

Yes,no issue with the connector. Have tried to unplug and replug again, tried to on off mutiple time, tried to change colour from apps and from the button, and also have tried to reconnecting the extension connector. But still the same
