Export option not showing in dropdown

I’ve just installed this and would love it to work (I have a staging site to merge with live tomorrow!) but it’s just not showing as a bulk option.
I’m using Yoast Duplicate Post which also hooks into this dropdown – but I don’t see your option even if I disable that. And thoughts?

I’m having to use quite a lot of plugins for this site – but any clues for incompatibility from the list?
