Target Device is iPhone only but iPads can download

I set the Target Device setting to “iPhone Only” but in the App Store, the app is listed as having iPad support and can be downloaded on iPads. The app is called Treads! and is currently in the App Store. Is there a different setting I’m missing? The game is not meant to be played on an iPad and I would like to restrict people from downloading it and playing it on an iPad.

This is how the app store works. iPads can download iPhone apps, because they can run them just fine.

iPhones can not download iPad apps because the screen isn’t big enough on iPhones.

Nothing you can do about it, just how they’ve set up the app store. Best you can do is make the regular one, then an HD version that’s iPad only and hope people buy that one on ipad.
