TaxCaster 2024 bug

I've been using TaxCaster on iPhone for years. I just updated to the 2024 version and entered my info.

 

To my surprise, when I add income to "Total dividend income", the amount due goes ... down. Not up. For example amount due is $20,534. with Total dividend income set to $0.

 

Now I change Total dividend income to $10,000. Amount due goes to $19,634, meaning I would owe LESS in taxes. That is just wrong.

 

If I change Total interest income, it goes the correct way. Adding $10,000 here changes Amount due to $23,314, meaning I would owe more in taxes.
