Curently the values for service doesn't get that set.

@samip5 can you try using the branch in #65, I cant test this because I am not running dual stack but I added this support to all three of the services we have.

I'm not exactly sure how I would test drive it, when it's in a branch and not a published chart?

It does however syntax wise look right.

I merged it, a new release will be generated shortly for it. Just respond here if your not able to get it working 😀
