Hi there,
Are you using Styler for the formatting? If so, you will want to look at styling the SFEs (Styler Formatting Elements). These are automatically generated by Styler and are hidden by default. You can enable them in the preferences in order to view and modify their behaviour.
BTW, there are also UFEs (User Formatting Elements) and GTEs (Generated Text Elements) which you may encounter and need to style in a similar fashion to SFEs.
