Zooz double plug child devices not shared correctly on mesh

Hello -
I have a Zooz double plug set up on a C7, and shared via Hub Mesh to a C5.
On the C7, the child devices for each side of the plug correctly report power and state, as does the parent device.
However, on the C5, using the linked plug, the children do not report power nor state. The parent device is correct, but both children show as off with zero power, even though the original device on the C7 shows everything correctly.

I'm using the native hubitat driver.
