Bug in UITableView: Why is the section header covered by an row after deleting an row?

Question

When I delete a row like this, and then scroll a little bit, one of the rows of that section happens to cover the section header.

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [dataManager deleteValueAtIndex:indexPath.row];

        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

Is there any solution to this?
