HS and NEO uses separate item lists. So if you don't plan to use the HS studio, then you don't need to add anything to the HS lists.
When you say not appearing, do you mean that they don't show up in the list, or that they are in the list but nothing
shows up in the studio?
We got a) ID conflicts, what IDs does the old stuff have in your lists? Or b) you forgot to add <><False><False><><False><><True> to the end
of the lines, or remove the two <> at the beginning of each line on the old stuff? Maybe both?
