Tom:
Assume that all is via JMRI on your computer screen to either the USB connected DCC++ or Lenz system?
Not direct help with Lenz... but, emergency stops can bypass momentum. True for the NCE I use. Why idle vs. stop no idea.
Your DCC++ not controlling servo point motors... You mention that with Lenz controller that they work and are Arduino based so I assume DIY designs..?
Whose Arduino sketch so we might check accessory address requirements? There might be a subtle difference in just how the addresses translate between the DCC++ commands and Lenz. Both are being sent via JMRI and not native in the Lenz throttle?
