Sorry to hear this is still a problem. My Marantz 7702 K2 didn't like 4.0 either. The Integra before it did fine. I wish I was on this forum back then to know it wasn't just me. So much time wasted with Marantz support. I ended up, like others, adding phantom channels. But I would've still rather just put in the disc and listened vs. playing the digital files.
The current preamp (Lyngdorf) plays these fine. Shows input 4.0.0 and output 4.0.0. Denon - Marantz really needs to address this.
