I'm not sure why you are asking me to read the thread again, I'm not saying it is a loan/debt either. I'm saying that the POF verbiage is confusing. If OP's POF was confusing + bank verification resulted into another confusing verbiage - technically that could lead to rejection. Without looking at the POF letter, no one can tell what happened.
The only issue I see is that, just like how PCCs scanned in black and white lead to a non-appeal-able rejection, OP might not be able to appeal against this decision. Good thing is that OP is at 501 CRS, so technically another ITA is possible in a few weeks/months.
