I just installed the new firmware and was playing with it. As Wendy said it seems like the squelch seems to be really important here. I was missing most transmissions when the squelch was in the "recommended" zone, and catching most of them with it turned all the way down. I have tested on all my programmed DMR frequencies, and it picked them up and decoded them about 75% of the time. The remainder I am going to assume is proximity, or squelch or something causing the issue.
