Hiya Paul,
Thanks for using our plugins and welcome to the forums! Sorry about this issue you are having. Let’s try to find a solution for this, shall we…
To be able to support you, could you please share your system information with me? Here’s a handy guide how you can do that:

Also, can you please review our Testing for conflicts guide and let me know what you find?
Please make sure WP_DEBUG and WP_DEBUG_LOG are enabled on your site’s wp-config.php file. Any errors will display at the top of your page as you try to reproduce the conflict. I also recommend right-clicking your mouse and opening the ‘Inspect’ tool to see if any errors display in the console. Note what you find and please include it in your reply.
Thanks and I’m looking forward to solving this with you.
Cheers,
Andras
