2024 Taxable capital gains (TCG): Total income summary page shows TCG assigned to one spouse only

 

2024 TurboTax's Total income summary page shows Taxable capital gains (TCG) assigned 100% to me and 0% to my spouse even though the gains came from a joint non-registered account and my portion in the "Your percentage" field was marked as 50% in all relevant T-slips entries.

 

I expected that the TCG would be split 50-50. But it's not. Should it not be?
