Hey Janice,
Thanks for reaching out. I don’t find this exact same behavior with tickets, and so to help me investigate here I’m wondering if you can post your site’s complete, un-edited system information? Here’s how to do that: https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Next, in regards to the email text you’re referring to, that snippet would not remove the “Your tickets will be sent in a separate email” text. I actually cannot find this text in some test emails I’ve been sending—can you share a screenshot of where you see this text in your emails?
You can do so by uploading the screenshots to this thread. If you have issues with that, you can upload to Imgur.com, Flickr.com, CloudUp.com, or any similar image-hosting site; then just share the links to those images here and I’ll take a look.
Thanks!
George
