How to properly report capital losses shown on a T5008

I have T5008 forms for securities transactions that resulted capital losses. I am using the T5008 section to enter the required information and selecting capital gain as the income type. But I get a warning during the review that says I have losses reported as investment income. I have double checked that I have indicated capital gains on each T5008 entry. Should I just ignore the warning or do I need to fix something?
