I am entering a T3 slip for my mother in law. It has 6 boxes to enter. But the dividend income would 100% pop up on my father in law's T1 and everything else goes to my mother in law's T1. If I enter a big interest income on that slip such as $10k, it would bring the dividend income back to my mother in law. Why is there such an issue. How can we fix it?

I am prepare a return for my mother in law and and father in law. I am entering the T3 slip for my mother in law (individual account). All other boxes shows on my mother in law's T1. But the dividend amount from box 49 goes to my father in law. How to fix this bug?
