the-bootstrap theme jetpack carousel not loading

I want to use the-bootstrap theme on this site and also would the generic Jetpack carousel to load within image galleries.

This works fine when the old theme is applied but not the-bootstrap.

I appreciate the theme allows you to load custom carousels – but if I just want the Jetpack version what am I missing please?

thank you.
