Discussion box not showing

Dear all,

I’ve checked the

Allow Discussion box in edit mode manual
Allow People to Submit Comment to new post in Setting – Discussion
Comment box in Screen Option

I can see the discussion box in the View mode of the post, but in the edit mode, preview mode and the final posted blog, the comment box is just not there

I’m using Lovecraft theme.

Any idea?

Thanks
