DJM-850 strange BPM behavior

Hi,

Could anyone explain me the bmp counter behaviour on the 850?

When its set to "auto", it measures the bpm of which channel? - in my opinion its not working correctly and there is some bug in the software...

I have loaded 2 tracks - one on channel 1, bpm 174

second one on channel 4, bpm 103.

 fired channel 4 only and when I cued channel 4 or the master, the display was showing 103.

When I fired the channel 1, cued only this channel, the bpm was blinking like its counting, and it showed stable 103.

So I muted channel 4 so only the channel 1 is in the master and it was showing 103. When switched the cue to master only, it was blinking and displayed 103.

When I stopped the track on channel 4 so only channel 1 was playing, it was still calculating as 103.

Could anyone please explain me what bpm is on the display? - how can I tell which channel should be measured? I was expecting it will be master or the cued one but according to the test above, it doesn't care even its blinking and calculating.....

Thanks!
