Era 300 rear driver is silent (with Arc Ultra)

The side tweeters on the Arc Ultra are “overpowering” the bonded rear surrounds.
Side channels are virtualized by both the Arc Ultra and Era 300’s. While you can use “Surround Audio” features to dial in the sound level of your preference there are a few important things to keep in mind:

Surround Distance Slider Behavior: The surround distance slider adjusts the sound level for both the Arc Ultra and the surround speakers equally. This is the intended behavior.

Adjusting Rear Sound Levels: The surround distance setting can be modified to influence the output level from the rear speakers:

• Setting it to “Less than 2 feet (0.6m)” reduces the volume from the rear speakers.

• Setting it to “More than 10 feet (3m)” increases the volume from the rear speakers.

Perceptible Differences: While the surround distance slider adjusts the levels equally for both the Arc Ultra and the surround speakers, testing has indicated that listeners may perceive differences in the sound from the listening position, as described above.

Impact of Trueplay: The surround distance setting is disabled when Trueplay is active, as Trueplay automatically corrects for this. To adjust the surround distance, Trueplay must first be disabled.

There is no audible output from inner woofers when Era 300 is bonded as rear surrounds.
This is by design. The rear speakers are designed to disperse sound throughout the room, rather than directing it to the listener exclusively. 

The Era 300 plays rear channel audio through its height array.
This, too, is by design. The Era 300’s DSP (Digital Signal Processing) leverages either the rear height tweeter OR the outward-facing tweeter/woofer to create the intended sound experience. Because of this, when you play the Dolby test track, you might notice that rear height channel as being active during rear-channel playback. This is expected.
