How to edit the Stroke and Shadow in Closed Captions Appearance Settings

I have Adobe Premiere 24.1.0. When working with Closed Captions, I am finding that the options I have for editing the text is limited. Typically, I can see under the Appearance bar, the options to edit the text Fill, Stroke, Background, and Shadow. Currently, I am only seeing the options to edit the text Fill and Background. Can you help me figure out how to edit the Stroke and Shadow? I am in the Captions and Graphics Workspace. Thank you!
