I'm not sure what's happening there, but if you open your score, tap the center of the screen to bring up the song overlay, tap the second icon at the bottom left and then tap "Crop", you can adjust (or clear) the cropping to prevent the problem. If that isn't the issue, then it's most likely the page scaling mode. Tap the icon at the bottom of the song overlay with blue arrows showing the stretch direction. Change the default page scaling to "Fit Screen" and you should not longer see parts of the page cut off.
