Inconsistent button styles in React application

The community member is building a website using the React library and is experiencing inconsistencies with the button styles. The available variant for the Header buttons should be "secondary", but the variant "bg-background-alternative" is being applied instead, causing all buttons to look the same. The other variants work correctly, but for some reason "alternative" is applied instead of "Secondary". In the comments, the community member has found the issue in their tailwind.config file.
