When I create a cc library item, I usually have created it in a specific spot on the page. Example, I have a header I like to always sit in the top right corner of my page. If I need to edit the library item, maybe by updating the text or color in my header, it will not save in the same placement I had originally created the item. In order to update the library text AND keep my original placement, I have to delete the library item and create a brand new one.
