Patricia, you star!
Thank you so much for your help with this. I totally get it now.
We’ve decided, going forward, to make as few customizations to the edit-event.php or indeed any capture screens, as this seems to fall over when updates are made to the plugin’s core functionality.
Please thank your team from us, and thank you personally for you brilliant assistance and support with this issue!
Many thanks.
Kind regards,
