Okay, I need to make an adjustment to the code because it seems that under certain circumstances, if you move a plant from category to category it can mess up the privacy settings. I have adjusted it for you Marilyn and there shouldn't be any more problems. Plants that are hidden should show hidden now.
Your Scilla category is the only one that is not hidden and you have 11 plants in that category. Other than that you list should be 100% private.
