OJS 3: show Keywords in bootstrap theme?

Hey there,

problem: If one sets the OJS site (v.3) to the standard theme, the proper keywords are displayed at the respective article page.
When choosing a bootstrap theme however, there are no keywords shown.

I could not find a way to set this option to “visible” - is there a chance to stick to bootstrap theme AND to display the keywords on top of the article page?

Thanks a lot!
