Feed Level Explicit Tag Not Setting

In the podcast settings I have set the default and all sub podcasts to explicit, but when I look at the XML for the podcast it says:

<itunes:explicit>clean</itunes:explicit>

I also set it per episode and those set properly. This is an issue as podcast readers and specifically itunes view it as clean at the root level and this is not true. How do I go about rectifying this?
