Using nodeAffinity to deploy the admission controller

When deploying Couchbase with helm, the admission controller(AC) is deployed to a random node in the cluster. I have a customer that wants to pick which node/node group, that the AC is deployed to. I've altered the a values file to replace the defaults, with a nodeAffinity, however, it is not picked up by the AC deployment. When using nodeAffinity with the operator or the cluster "server" pods, the affinity criteria is accepted and the resources are deployed in the correct nodes.
