That is because you added it to a compound selector. A compound selector uses multiple selection criteria and applies the styling to an element that meets at least one of the selection criteria. If you don't want a style to be applied to the others, you need to have a separate rule for just the categories. You can still keep the compound rule to apply the shared styling.
