There are no dedicated object types for prologues, interludes, and epilogues within Shaxpir. As a result, they must either be classified as chapters (messes up the chapter numbering in the table of contents), scenes (doesn't feel right), or front-matter or back-matter (not really what those classifications are used for).

As a result, if you want to export a table of contents you have to intentionally mis-classify these entries in order for them to show up properly in the contents while not affecting chapters.

On a related note, I've found that chapter export options don't always work. On more than one occasion the table of contents will include object types which I have disabled on the export screen. I suspect that occasionally these export options get stuck in an 'on' mode and cannot be disabled despite what selections are made in the GUI.
