When I import my slips from the CRA, Proceeds or Settlement value (21) is added into my total income instead of the difference between the Proceeds or Settlement value(21) and Cost or Book Value(20). Both fields were imported correctly.
This appears to only be a display error in the initial import summary as when I goto my Income summary from the drop down, my Total Income is calculated correctly.
This really threw me into a loop as I was panicking if my Bank uploaded the incorrect information.
