Welcome to the forum – great to have you here!
Fixing the debt-free cash flow totals should be pretty straightforward. Enterprise DNA Expert @Greg has put together an outstanding series of DAX Patterns on fixing totals. I think those patterns should be directly applicable to your problem here.
Overall, you will get the best/fastest/most specific responses on the forum if you post not only a clear description of your problem (which you’ve done), but also your PBIX work in progress, and a mockup of the results you want to see.
If your data are sensitive, I can point you to some great tools and videos we have to help you mask confidential data for posting.
I hope this is helpful.
