Thank you so much for your help, @Anonymous . I believe I have found the solution to my issue, which was simply a setting on the Koinly Tax Reports page which removes all derivatives (Margin/Futures) from your capital gains/losses "in case you want to claim these separately," no idea why they'd default to that setting but.. hopefully that's all I needed. My total losses are now showing correctly in the report! I'm posting a more detailed solution for future people needing help with this in a separate comment. Thanks again 🙂
