Editing feature disappears

I gave been working with this app the past week since Pocket Wavepad crashed due to the 4.3 update. On two occasions I recorded songs, edited them, but after saving, the wave-form totally disappeared in editing mode - it looked like the file was empty. The file still played from the Title List and opened in editing mode, but it was otherwise empty. Has that happened to anyone? Luckily the file could still be sent to my computer for further editing....but until this glitch is fixed I wont use this app for anything urgent!
