Strapi v4 - Extending theme config does not override one of the colors

These are my theme settings in src/admin/app.js.

export default {
  config: {
    theme: {
      colors: {
        primary100: '#eff8f7',
        primary200: '#c4f0eb',
        primary500: '#8ae2d6',
        primary600: '#60bdb2',
        primary700: '#0a7a7f',

Now, it does override all of them, except for the last one for some reason, as you can see in the image below, the button is still purple.

Never mind, I realised there are additional properties for the button color. It bugged me out because for some reason it previously worked just with the ones above.

Hi, I am having the same problem. How did you manage to remove the additional properties for the button color?

buttonPrimary500: yourColor,
buttonPrimary600: yourColor,
