Hi Marc,
Thanks so much for reaching out!
Other than the solutions that you have already found, I don’t have much more to suggest. You can bulk edit your tickets under WooCommerce < Products, and change them all at once there, instead of one at a time. However, moving forward, you will have to manually change each of your tickets to Visible as well.
You can also add this idea to our Feature Requests, as we tend to implement ideas based on customer feedback, so your input is greatly appreciated:

Let me know if you have any other questions on this topic!
Thanks,
