Issues with the Color Picker in the Style Guide When Using Hex Codes

Hi everyone, Is anyone else experiencing issues with the color picker in the style guide? I copy/paste hex codes in the respective field, exactly as it's shown in this vid - https://www.youtube.com/watch?v=LPHcehrwIzs - but it's not working. I already duplicated the project I'm working on to see if that might solve it but nothing happens. Thankful for any pointers as to what the issue may be. 🙏
