All posts linked to category not displaying in the frontend category page

[mrcks]

e.g. https://www.dipanddoze.com/blog/10-minutes-with/

This category has three posts linked to it.
Looking in the table mst_blog_category_post, I see links to the category and the three posts.

Capturing the query from within: Mirasvit\Blog\Block\Post\PostList - getPostCollection()
then running directly in the db, the results consists of three post records.

However, the frontend only returns 1 on the posts.
Cache has been cleared, code hasnt been modified.
Very odd.

Looking in the composer.json of the module, we're at v1.0.32 yet I see on github there is now v1.0.39.

I cant see any release notes, therefore is the issue I mention a known issue and will an upgrade resolve perhaps?
