Cannot set app to iPhone only - ios

Question

I have the following settings on my app. It should be iPhone only.
Like you can see I also get the iPad simulaters and my App is rejected becaused it crashed on iPad.
Does anybody know what is going wrong? Do I miss a setting ?
Thanks in advance !!
EDIT
Here is what the crash report says what apple send to me.

Answer 1

Any iPhone App , will run on iPad even if you restrict to iPhone in your Project Settings,Your App will be shown with a Scaled view for iPad such as Zoomed in version. If your App got crashed on iPad, then you would have to handle it, try to figure out using the reasons given in Resolution Centre or by running your app on iPad Simulator.
