Subtitles "use track style" issue

I want to move the subtitles around the screen in different parts of the video, so I unchecked "use track style" but now I no longer have access to many settings that were under track style, like transform, drop shadow, stroke, background (this is the one I need).

The only thing available now is "caption style" (see attachment)

Am I missing some other way to do this, I really need the background settings.

I'm on Resolve 16.2.7.010

Help !
Any ideas?

I need some subtitles without a background and some with a background.
But when I turn off "use track styles" it doesn't change the background.
And if I change the background, the background changes for all subtitles, whether "use track styles" is selected or not for that subtitle.

Help !

same here!
Why the background didnt linked on Text - Width. ???
The background think is needed for each caption , but of course , the width must be linked to the text -width.. the only way this would make sense.
