Pioneer DJM-REC app issue?

Well I bought this $10 app. Yesterday I tried it out for the first time for my set at SF Pride cause I don’t own a 900 mixer. I was the opening DJ and tested to see if I was getting signal in the app which I was so I figured it was fine. But I listened back to the recording today and it only recorded 1 of 3 channels and it also recorded pre fader and effects. You can hear me searching through and cuing up songs. Has anyone else had any issues or good experience with this app? Maybe the mixer’s firmware needs updating?
