I don't think that the list of in-app purchases is accurate in the app store. I have purchased all my altos through the app store, and that list did not even remotely match what I had purchased.
I bought 3 more to get me to my 10. I then upgraded the operating system on my H9 and H9 core, and "Restored Purchases" through the iPad app.
BOOM
H9 and H9 Core have all presets unlocked, confirmed.
Thanks!
