DetailText loading in incorrect space in UITableViewCell - ios

Question

Its hard to explain to images will help. When the UITableView first loads, the detailText is above the textLabel - as such:
But when you move the tableView around a bit, it corrects itself, as such:
Here is my code for adjusting for everything I feel is applicable:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
cell.detailTextLabel.numberOfLines = 0;
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
}
if (indexPath.row == 0){
cell.textLabel.text = #"Two";
cell.detailTextLabel.text = [self.rules objectForKey:#"two"];
}
if (indexPath.row == 1){
cell.textLabel.text = #"Three";
}
if (indexPath.row == 2){
cell.textLabel.text = #"Four";
}
if (indexPath.row == 3){
cell.textLabel.text = #"Five";
}
if (indexPath.row == 4){
cell.textLabel.text = #"Six";
}
if (indexPath.row == 5){
cell.textLabel.text = #"Seven";
}
if (indexPath.row == 6){
cell.textLabel.text = #"Eight";
}
if (indexPath.row == 7){
cell.textLabel.text = #"Nine";
}
if (indexPath.row == 8){
cell.textLabel.text = #"Ten";
}
if (indexPath.row == 9){
cell.textLabel.text = #"Jack";
}
if (indexPath.row == 10){
cell.textLabel.text = #"Queen";
}
if (indexPath.row == 11){
cell.textLabel.text = #"King";
}
if (indexPath.row == 12){
cell.textLabel.text = #"Ace";
}
CGRect frame = tableView.frame;
UIButton *addButton = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width-70, 10, 50, 30)];
[addButton setTitle:#"Get" forState:UIControlStateNormal];
addButton.titleLabel.font = [UIFont fontWithName:#"Avenir-Black" size:14.0f];
addButton.backgroundColor = [UIColor redColor];
[cell.contentView addSubview:addButton];
cell.detailTextLabel.numberOfLines = 0;
cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap;
[cell.detailTextLabel sizeToFit];
return cell;
}
The row height:
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *str = [self.rules objectForKey:#"two"];
CGSize size = [str sizeWithFont:[UIFont fontWithName:#"Avenir" size:17] constrainedToSize:CGSizeMake(280, 999) lineBreakMode:NSLineBreakByWordWrapping];
return size.height + 40;
}
