I only had my Canadian passport listed on my Nexus, because I wasn't aware that I had to list other citizenships and passports (in my case, UK passport, which I obtained after my Nexus - turns out I should have added this immediately after getting it). CBSA didn't care, only CBP did. To this day I've not seen any official documentation that explicitly states you have to declare all citizenships and passports (although on the application form you can enter multiple), yet here I am with my Nexus revoked and my reconsideration request denied. So take that as you will. I have attempted to re-apply ater waiting a couple of years since the revocation but it's been stuck in pending approval for nearly 2 years now.
