Every time we generate CRD, we need to change it (beta branch)

When we use the command "operator-sdk generate crds", we have to change the CRD so it works.
This is necessary, because when we include podTemplate in the Custom Resource Definition, we get and an error associated to x-kubernetes-list-map-keys and then we have to delete the second and third apparitions of "- protocol" and then it works.
I tried to find how to solve that without having to change the CRD every time but there wasn't any simple solution to that.
