Bankruptcy ch 7 provides a fresh start by the discharge of many--perhaps all--of a sole proprietor's debts. However, the price of that discharge may be the loss of non-exempt property rights (inventory, for example) or the extinction of critical lines of credit, that might make continuation of the business unfeasible.

In unusual circumstances, a district court may "withdraw the reference" (i.e., taking a particular case or proceeding...
You wrote, “They are saying even though we filed ch.7 we still are responsible for money owed!“
A: No, they are not saying that.
The bankruptcy discharge your personal obligation, but that did not release the lien against the property; that lean is the basis for a foreclosure action.
