Issues exporting using Ghost Plugin - Wordpress to Ghost

Hi,

So I’m attempting to export all blog posts for decisionireland.com to Ghost - However when I do export and import the json or the zip file it only partially imports. See attached image:

It only takes the first sentence or two of the posts and then asks the reader to " Read the rest" and redirects them to the wordpress website.

Curious if anyone ever came across a similar issue? Could this be the plugin not being tested since WP 5.7 ?

Any help appreciated.
