Joint account T5 divident etc splitting with spouse is not doing properly - always keeping full amount in mine after transferring % to spouse

When I say 50% is spousal portion it puts 50% in spouse but it is still keeping 100% in my return.

So I am payiong tax on full income even though only 50% should be there. For the dividend income I checked the lines 12000 and 12100 in a test run. This is a big bug. Please fix it. I checked my returns for 2021 also it did the same mistake. I have to now correct and resubmit to cra explaining the problem. I am surprised that Turbo tax testers missed this. The onloy tested if the % given is transferred to spouse or not, but for got to reduce the amount used bu spouse in my return.
