Links to Author Pages

So, I’m having issues with the page users are brought to when clicking on a guest authors name on the posts they have written. Originally when I installed this plugin, it all worked as intended. Clicking on an authors name brought the user to a page with all of the posts they are tagged in on the site.

Just recently, maybe within the last couple months, this has changed. Now, no matter who the post says is the author, clicking on that authors name at the top of the post brings the user to one singular author page, that of Timothy Murphy (the founder of the site and the only author registered outside of the guest author plugin). Going to the link and clicking on “Greg Moore” will show the issue.

I’ve gathered from other posts on this forum that maybe shortcode is my solution to this, because my website theme is not gathering information from the plugin, but have read through the list of available shortcodes and am not entirely sure which would solve my issue.

Help would be greatly appreciated!
