Hi David,
Thank you for your precious feedback. There is definitely an issue in our plugin (Grimlock for The Events Calendar) which will be fixed in the next update.
We’ll be back to you as soon as the update is available.
In the meantime, simply add the following code snippet to your website:
.tribe-events-single--classic .tribe-events-single-content .tribe-events-c-subscribe-dropdown {
display: none !important;
}
To add this code snippet to your site, we recommend that you paste it to the Custom CSS panel of your WordPress Customizer. Just go to your dashboard and navigate to “Appearance > Customize > Additional CSS”.
Pasting your code snippet there should do the trick for you.
Regards,
