BUG: Category Color Picker

[senseOPN]

After migrating to 26.1.1_5 I changed and added some firewall categories, but the color picker does not work!
You can select a color from the graphical color picker, but in the overview and in the rules, all of them remain black!

For me it works, are you sure you are setting the color picker correctly?

E.g., in Chrome you have to click the colored box to where the color is. If you only use the slider, the actual color picker stays on black.
