colors are only randomly displayed

Hi,
we assign the colors by tag.
The problem is that some colors are displayed correctly other “tags” are displaying only our default color (red)
in the database the colorcode is saved correctly
in the backend the color is displayed correctly
in the frontend in the html-code sometimes randomly the style background-color is missing and therefore it displays the default then.
here you can see a screenshot shows you the problem:

and here is the website and for example “Human Trafficking” or “Freedom of Assembly” doesn’t work:
https://legal-dialogue.org/topics

it’s not a problem of the Browser and not of the wordpress versions!!!

the funniest thing is, that I have a similar local instalation and there NO tag is working!!! They all have the default red…

the plugindescription want’s a plugin named “wp term meta”, I have not installed this and your link for this in the wordpress library doesn’t find anything

thankyou very much
