Unlike other types of hints, CSS code hints always show the existing property name/value as the filter. As a result, you will see only one hint (ie. the one already in the page) regardless of the cursor position.

For example, if you have b|ackground-color: #eeeeee; and the cursor is after the letter "b", you only see "background-color" in the hint list and the entire item is shown in bold.

Expected: Only "b" is in bold and all CSS property names start with "b" should be in the hint list so that you can replace the current property with a different property.
