Kotlin Additions color scheme

Hello,

I am trying to configure my Kotlin color scheme to match my Java color scheme. Setting values in ` Editor > Color Scheme > Kotlin Additions` doesn't seem to do anything...

Here is what it looks like in the preview panel (correct):

And here is what it looks like in the editor (incorrect):

There also seems to be no distinction between different "Modifiers" and "Keywords":

...but this appears to be the purpose of "Kotlin Additions". However, the changes are not taking effect in the editor. (?)

If anyone could assist me in diagnosing this behavior, it would be greatly appreciated.
