WP Shortlink Images Not Showing on Facebook.

Hi, When I paste the WP shortlink into a FB post, I’m getting my featured image as the image in the post, not the image in teh actual post. has been working fine for 2 months with the post image showing…today it’s suddenly my featured image. Any ideas why? I logged out/in, restarted wp share in jetpack, even tried posting an earlier post that definitely worked and looked good, still haveing issue. Thanks in advance……

site is gymjams.club, the fb page is facebook.com/gymjams.club if you need to actually ‘see’ it.

thanks again,
j
