Yoast SEO making my site titles disappear!

Yoast SEO is making my site titles disappear.

I have read it has something to do with breadcrumbs but no clue how to resolve.

Any clue on how to fix this?

Any help would be greatly appreciated.

This is resolved - just had to enable the breadcrumb option, in the advanced settings of of Yoast SEO …in case anyone ever comes across the same issue.
