I am also getting the error message that the account has been deleted.  Please advise.

I converted from desktop and QBO marked all the job expenses as billable.  Since all my old jobs now have all these unbilled expenses, I am unable to inactivate them.  There are thousands of them.  I don't have the time, resources or patience to manually uncheck the billable expense box.  All these transactions are polluting my customer module.  There must be a solution for this.  Any help is appreciated.

Thank you!
