I am trying to unlink account.move.line through wizard on a button but error is getting called as "unbalanced entry debit - credit", Below is my code and screenshot of error for reference.
I can understand it wants to delete the journal items too , but how to do it?

def confirm(self):
    if not self.move_lines:
        raise UserError(_("Please check no any lines Available in wizard."))
    move_lines = self.move_lines.filtered(lambda line: line.select_item == True)
    for line in move_lines:
        line.move_line_id.unlink()
    return {'type': 'ir.actions.act_window_close'}
