Nope, that link is empty for me and the link I added is the public list you have of all the plants and it's not there. There must be some kind of glitch.
What I would do is go into your edit mode or click on the " In your list!" link from the entry and change the status back to "choose from below" and then uncheck it from whatever category you have it from and then click to save your changes. Then go back to the entry and add it again, checking the 'Have' status and whatever category you want and then save it.
