Bug in current release? – Relax Sounds: White Noise App Review

This 5-star app is a must-have for helping our daughter get to sleep. However, the current version appears to have a bug that prevents you from adding/removing items from the favorites list. This was on my wife's iPhone 5s with iOS 7. Will wait for more reviews before I update on my iPhone 6.
