I would like more information about the print, preferably a scan of an actual print page. Is the text in each verse line-numbered? Is the text in each verse shown in poetic or prose form?
I don't think this is just a matter of centered headings, even though you have followed the format given for centered headings, blank line before and after. Headings that are centered in print are not always treated as braille centered headings for a variety of reasons that I'll be happy to discuss as soon as I have more information about the surrounding text.
So if you can send the information I have mentioned above, that would guide me to a more precise answer.
