helm install error: "Invalid value: 30269: provided port is already allocated" to dmaap and contrib

I am receiving  the following error:

ubuntu@testmaster:~/sep17/oom/kubernetes$ helm install ./onap -f onap/values.yaml --name dev --namespace onap

Error: release dev failed: Service "dmaap-dr-prov" is invalid: spec.ports[1].nodePort: Invalid value: 30269: provided port is already allocated

ubuntu@testmaster:~/sep17/oom/kubernetes$

In this page: https://wiki.onap.org/display/DW/OOM+NodePort+List , port 69 has been registered against “dmaap" and added to OOM (8/29/2018).

However, the same port had been already used by "contrib" for nginx (8/14/2018), but was missed to be reserved in wiki page. 

ubuntu@testmaster:~/sep17/oom/kubernetes$ grep -r 69 *

contrib/charts/netbox/charts/netbox-nginx/values.yaml:  nodePort: 69

dmaap/charts/dmaap-data-router/values.yaml:      nodePort2: 69
