Color ratings are gone

[Kazzpix]

After updated to Lightroom Classic to 11.4, all color ratings are gone. Which means even if I clicked a certain color, no picture shows up. Also I remember some files rated like green or blue, those files are not rated anymore. No pictures are not rated in any color. Now I can't find any files by the ratings and this is a big problem for me.
How do I fix this problem?

LrC 11.4.1 released last week includes a fix for what you describe.

Oh, I’m sorry just checked but the version is 11.4.1 but the problem is still happening. Thanks anyway.

Color labels are actually text fields, so when an image has 'Red' in that field, Lightroom will show a red label. You can change this however to something else, so that 'HDR' will show a red color or 'Still work to be done' is red. That is defined in the label set. If your label set got changed, then your label texts no longer match the set. https://helpx.adobe.com/lightroom-classic/help/flag-label-rate-photos.html
