Issue with guest author name in AJAX pagination

Hi,
I am setting up a news site (local env at the moment) and using the Molongui Authorship plugin to handle co-authors and guest authors. For guest authors, I am not creating a WordPress user.
On initial page load, the correct guest author names are displayed on the block. However, when I navigate to the next set of posts via AJAX pagination, the author displayed reverts to the actual post owner instead of the Molongui guest author.
Additionally, I have noticed the same issue when viewing the page inside tagDiv Composer.

I really do not want to create fake WordPress accounts for guest authors (I have tested this, and it works but is not ideal).

Any hints? Thank you.
