UITableViewCell data not showing up *initially* in UISplitViewController

Question

I have a generic UISplitViewController (UITableView in the RootViewController and other stuff in the detail view)

I have modified UITableViewCells in 2 ways:

1. The rows have a height of 55
2. The UITableViewCells contain both a UIImage and UILabel

There are 50 rows total

PROBLEM: When I launch the app, the first 13 rows (the ones that are visible) DO NOT DISPLAY. I get empty rows.

If I scroll away from the first 13 rows and then scroll back…THEY APPEAR.

Any thoughts on what I'm doing wrong?

Here's my relevant code (I omitted general stuff like dealloc).

////////// header file /////////////////////////
#import <UIKit/UIKit.h>

@class c_cell;  // my custom UITableViewCell class (with cell height of "55")
@class DetailViewController;

@interface RootViewController : UITableViewController {
    DetailViewController *detailViewController;
    IBOutlet c_cell *cc;
    NSArray                 *cell_names;
    NSArray                 *cell_tlas;
}

@property (nonatomic, retain) IBOutlet DetailViewController *detailViewController;

@property (nonatomic, retain) IBOutlet c_cell   *cc;
@property (nonatomic, retain) NSArray *cell_names;
@property (nonatomic, retain) NSArray *cell_tlas;

@end


/////////////////  end header file /////////////////////

At the bottom of viewWillAppear, add [[self tableView] reloadData];
