If the filters only allow channel 35 that's what the optics should be tuned to. I'm not sure how to verify that, since clearly you set the channel and yet the show commands do not confirm that.
All that comes to mind is to confirm the actual frequencies of those channels on the DWDM filters (we've encountered some incompatibilities with Ericsson OTN equipment - their bands didn't always exactly aligned with ITU channels).

What software version are you running on those ASR9k?

kind regards
Pshem
