What is the purpose of Statement of Investment Income sub-section of the Capital gains profile?

I have already entered/imported my T3 and T5 forms and so I would expect that the Statement of Investment Income would already have prefilled entries for say "Actual amount for eligible dividends ..." but instead is shows 0.00.

If I have already entered my T3s/T5s, I would have expected that amount from those forms would be reflected in the Statement of Investment Income sub-section, but it's not.

If  I manually add up the amount for eligible dividends from T3/T5 and manually enter to "Actual amount for eligible dividends ...", this increases the amount of tax owning.

Please clarify.
