I cannot delete a “ghost” collection. By ghost, I mean that when I go to my collections page, it isn’t there, yet it is visible in my shop.
What’s worse is that it is connected to another collection. They share the same products and information. I cannot delete the “ghost” collection because it is not showing up on the collections page. It’s not there, so I cannot delete it.
Perhaps it has been set within your theme if it is showing in your frontend. Just confirm the same occurs in different browsers. If it does can you provide screenshots or links to the page?
