Loan Defaulted Sept 30 - But Why is the Loan Balance Still Increasing?

First off, I want to thank this incredible, supportive, and extremely kind community for all the help you’ve provided me for the last several months. You’ve all helped me tremendously especially with my severe anxiety over everything.

This post is literally the title : the Firstmark loan balance keeps increasing even post default. Everyone else’s loans on this subreddit stopped increasing its balance after default and I don’t know why mine is doing that? It defaulted at approximately $46,500 and both in October and now in November, it’s increased its balance (now it’s at $47,400) according to the credit report.

Before I ceased communication with them (they wouldn’t accept a settlement offer below 85 percent or 65 percent if they were feeling kind that day, I can’t afford either), I had asked why the balance increased, this was back in early October. They said it’s still a loan even if it’s defaulted.

can anyone tell me why this is happening? Is it in the loan terms? I have to pull back out the loan terms as it’s been over a decade since I last looked at them. Is there any way to get the balance to stop increasing, because how am I supposed to one day settle on this if my balance goes up tens of thousands of dollars while I try to save money for a settlement?

Any help that can be provided would be amazing. I’m so lost and scared right now. Thanks again.
