uBR10k Upstream bonding with only one channel

Hello,

I have been working on a 16x4 configuration with a uBR10k in a lab using docsis 3.0 modems. The modems will connect to the cmts fine and the downstream will bond with 8 downstreams just fine. (8x4 modems) However, it appears that the modems will only bond with one upstream channel, and that channel will vary from modem to modem so its clear they're all being used.

Heres my configuration:
