Visibility of paid and free articles

I have quite a few paid subscribers to my newsletter and one of the perks they get is not having to see ads that are sent in the free edition. That's why I send out two versions of the newsletter - one for free subscribers with the ads, the other for paid subscribers without the ads.

It works great on email, but it's a bit of a mess when you see the website because it's doubling every post. I was hoping that if I checked the free checkbox next to web audience and vice versa, that it would only be displayed to free audiences or paid audiences, depending if they were signed in or not, but this doesn't seem to be the case.

Does anyone on here a similar problem? Does anyone have an idea how to display just the posts for every group of subscribers?
