DJM-REC doesn't record audio directly from the mixer.

Hi there,

for some reason, my DJM-REC doesn't record directly from my mixer. I already restarted all the settings but it still doesn't work. It only records through the iPhone mic. I have nexus 2. 

Also, it's blurry on the top of the settings where it says "Audio Output" so I can't change it. 

Please LMK how to fix it.
