Hi Juan!
Thanks for reaching out to us! I am really sorry your are having this issue!
Unfortunately, this is a known issue and the team is already working to fix it as soon as they can.
As you said, the info is saving if the user edits the fields through his tickets page.
The only workaround at the moment is to downgrade Event Tickets Plus to 4.4.1. Here’s a guide on how to accomplish this > https://theeventscalendar.com/knowledgebase/downgrading-plugin-past-version/
I will change this thread status to “Pending fix” and link it to the bug report so we will let you know as soon as a bug fix is released.
Best!
Victor
