Hi there,
I checked and it’s correctly displaying the image and description. Here is the code from your site
<meta property="og:title" content="Dungarvan Photographer Bunmahon Beach Engagement Photos" />
<meta property="og:description" content="'I do' photography - Safekeeping LOVE forever." />
<meta property="og:url" content="https://idophotographydungarvan.ie/portfolio-item/bunmahon-beach-engagement-wedding-photographer-waterford/" />
<meta property="og:site_name" content="Wedding photographer Waterford Cork 'I do' photography" />
<meta property="article:publisher" content="https://www.facebook.com/idophotography" />

And the description is
'I do' photography - Safekeeping LOVE forever
Facebook only displays what it can scrape from your page. Perhaps it’s your page that is displaying wrong OpenGraph Content especially the description? You can try adding excerpt to your posts manually (https://napitwptech.com/tutorial/adding-manual-excerpt-in-wordpress-posts/).
Usually, those OG contents are derived from excerpt (except SEO plugin adds their own), and excerpt is generated by Wordpress by removing codes, HTML, scripts, and shortcodes. And since you build your posts in the builder where all content are wrapped with the shortcodes, then the content you’re expecting to see in the excerpt is different. Hence, the solution is manually adding the excerpt, Wordpress added that feature for that purpose 
Thanks!
