Closed Captioning Sidecar Formatting Issues

Hi,

At my organization, we work with caption files for television broadcasting. We're currently experimenting with using Premiere Pro to generate those captions for our workflow, however we've run into some issues with doing so. Whenever we attempt to export a sidecar file with our formatted closed captions, the exported file does not keep the formatting of the captions that we set before exporting, but only the text in the default Premiere format is displayed. Does anyone know why it may be doing that? Is there a workaround or solution to this problem?
