Used to love love, now just love

Ive tried to reach company because ever since Apple Download from 2 downloads ago, I have only been able to edit one picture at a time, save it, then I have to close the app, then reopen it and start again. Ive tried ex-ing it off my iPhone 5s & re-downloading the app, but it still doesnt work. Please PerfectPhoto, help me! If it wasnt for this issue, it would be a 5 star vote for me. Please HELP!
