Incorrectly saving to camera roll

App is running and I was able to unzip a folder of pictures I transferred. However, When I save to my iPhone camera roll, the first picture I saved to my camera roll is saved over and over again (not the current picture on my screen). Seems like a bug to me. The only way I found to get around this is to save the first picture to my camera roll, completely close out the app, reopen the app, select the second picture, save, completely close out the app, reopen the app, select the third picture, save, repeat for the following pictures I would like to save. It would be helpful if this was fixed so that you could just swipe through your pictures and tap the share icon to save each picture without having to close the app after every save.
