“View” button missing since plug in update

Hi there

For various reasons I did not update the plugin for a couple of years. I have now done so, and notice the “View” button which used to be next to the listings is no longer there.

Here is the page with the updated plug in (v 5.11.1)
https://www.uckfieldchamber.co.uk/business-directory/wpbdp_category/accountants/
– no button

And here is the pre-update version (I made a copy on a staging URL). The plug in is v. 5.3.4
https://uckfieldoriginal-hyaj.temp-dns.com/business-directory/wpbdp_category/accountants/
– notice the “View” button

Not sure if it was removed, or whether something else is causing it. I have done quite a lot of customisation using CSS but the button is not in the source code so it’s not a CSS issue.

Any help really appreciated.

Thank you!
