Strange new frame at the first dot

[denisdbv]

I use this code:

self.pageControl = [[SMPageControl alloc] initWithFrame:CGRectMake(110, 496, 100, 10)];
self.pageControl.numberOfPages = 6;
self.pageControl.currentPage = 0;
// green point
[self.pageControl setPageIndicatorImage:[UIImage imageNamed:@"page-dot.png"]];
//white large point
[self.pageControl setCurrentPageIndicatorImage:[UIImage imageNamed:@"page-dot-current.png"]];

[self.pageControl setImage:[UIImage imageNamed:@"page-signup-dot.png"] forPage:5];
[self.pageControl setCurrentImage:[UIImage imageNamed:@"page-signup-dot-current.png"] forPage:5];

After run and scrolling, the first dot became a whitish border.
