TKCalendarMonthView does not display current month after reload

[Nikooos]

I'm using TKCalendarMonthTableViewController to display events from the EKEventStore which I have to ask permisson to first. So when I have permission I'm reloading the monthView, but then the current month is not displaying. If you use the arrows, you can go to the next month which display correctly and then you can slide back to have a perfectly displaying month. But why isn't it showing up in the first place? Any thoughts?

Another crazy thing is that sometimes, after a while, it does display the code. But this takes very long and not set to a particular timeframe. First the image not working and second working, but only after scrolling through months.

Code is below

#import "MonthCalenderViewController.h"

@interface MonthCalenderViewController ()
@property (nonatomic,strong) EKEventStore *store;
@property (nonatomic,strong) NSArray *calendars;
@end

@implementation MonthCalenderViewController

{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    [self.monthView selectDate:[NSDate date]];

    self.store = [[EKEventStore alloc] init];
    [self.store requestAccessToEntityType:EKEntityTypeEvent
                          completion:^(BOOL granted, NSError *error) {
                              if (granted) {
                                  self.calendars = [self.store calendarsForEntityType:EKEntityTypeEvent];

                                  [self.monthView reloadData];

                              }
