There is actually nothing wrong with your device and as far as I can tell your recording should be ok.
But there is one important thing you need to know when recording with the uTrack24: all 24 audio tracks are recorded into 1 interleaved wave file. Similar to a stereo wave file which contains only 2 interleaved channels, we are creating a single wave file that containes all 24 channels. The reason we do this is that most USB storrage devices will not be able to simultaneously write 24 large files without running into performance problems which would then cause drop-outs. So instead we write this single 24.channel file. (which could also be several files if the total file size hits more then 2GB)
So if you want to use the recorded tracks in your DAW, all you have to do is to use either the Cymatic Audio WavTool (Mac/PC) or Playlist Editor (PC only) to import the files to your PC or Mac.
Both tools will
1. Copy the recorded files to your hard disk
2. Create 24 single mono wave files from the 24 channel wave file
3. Join files if the recording had been split (due to 2GB file size limit)
Please also refer to the uTrack user manual chapter 13 uTrack 24 File Formats
