The good waveform is noticeably more symmetric than the problematic one. My first guess would be that somebody's dropped that microphone at some point. Try a different mic and see if that solves the problem.
If it doesn't, there could be some source of asymmetry in the signal chain. Are you using a compressor on this channel? Or if you're using an analog desk, there could be some DC bias creeping in somewhere. If changing the mic doesn't help, switch it to a different channel on the mixer. This is the kind of issue that you can only resolve successfully through trial and error.
