CDJ 900 BPM counter not showing up

Hello all,

I'm struggling to find a solution to the problem I'm having here on the forums. I had used my equipment at a NYE party the other day and let other people use my equipment as well. When i returned to the decks, the BPM counter was no longer shown on the interface and I couldnt change the tempo range either. 

I'm wondering if someone has either changed a setting on the decks to allow this or if it's potentially just a spilt drink scenario?

Thanks in advance
