Buttons are too big using Web AR.. please help!

Hi,

I’m using Web AR for a business card demo, I was wondering why the buttons ( default design and interactivity ) they appear larger than the screen size ( they cropped a little bit ) I’m not using my custom buttons these are the defaults zappar interface ( widgets ) please advise.

Thanks
