Cost calculator white screen death on mobile

Hey Guys, I there anyone who is using the @Cost Calculator128 plugin, I am getting screen death on mobile. It took my whole day just to debug why the screen was white on mobile and I started deactivating plugins one by one and found the problem is with the cost calculator. The problem is only on mobile not on large screens. I have tested it on all browsers but it seems the problem is on small devices. Please advice.

Thanks,
