I haven't been able to reproduce the problem so far.  When I've tried copying and pasting presets on an iPad directly on an H9, they pasted correctly.  What I did notice though is that if you've set the preset range on the H9 to scroll from presets 1 – 25 and you paste to preset index 26, H9 Control doesn't ask you if you'd like to change the preset range on the H9 to 1 – 26.  So, you can't actually get to the new preset until you change the preset range…  Maybe, this is the problem you were having?  In any case we'll have to add a dialog that asks you if you want to change the preset range…
