CMS Collection List locked

Hi I’m wondering why I can’t choose the collection list that I wanted to connect here.

@katrinka - You deleted the page you shared so that makes it hard to help you.

I encountered the same problem. Customer support only sends videos and articles on creating a collection, which isn’t helpful. Interestingly, many posts in this forum report the same problem, and all the answers suggest the same solution: unbind your collection. I’ve done that, and not only did I unbind all my collections and all components on my collection page, but I also had to create an entirely new site — just to encounter the same issue again. Now, I have two sites with locked collections that I can’t fix. Is there anything else I can do besides unbinding collections?
