Seek Buttons Broken Across Chapters

If you press 10s back mid chapter it works correctly, but if you press it at the beginning of a chapter such that it would bring you to the previous chapter, it seeks all the way back to the beginning of the previous chapter. Found while tapping it back 10s at a time trying to find where I missed something and then it starting jumping back chapters every tap (since it was at the beginning of the chapter every seek).
