Style Text and individual text element edits

I would like to universally change some text settings using Format -> style -> text styles. For gradual tempo change, my edits are reflected in the score and parts, but for staff and tempo text, they are not. I believe this may have something to do with whether specific text elements have been edited or not. If this is the case, is there a way to work around it so that my changes in the style settings for elements that have been previously edited are reflected in the score and parts?
