I am not sure wether this is the right place for my question. I am using org-reveal for building reveal.js slides.

The last line of my org file is something like that:

* bibliography:referenzen.bib

Since I am using reveal.js-3.8.0 I get two bibliography slides instead of one at the end of the slide deck.

Normal Html export works correctly, there I see only one bibliography header.

Any hints what's going wrong?
