Am I missing something here or are homebrew subclasses not playable yet?

I've got homebrew content turned on, master subscription, I'm able to add other homebrew content but can't play a subclass? What am I missing?

On the first page of the character builder there are a few source toggles. Homebrew is off by default.

Yeah, it's toggled on. I can add Homebrew equipment, feats, etc,  but subclasses aren't there. I've also added the subclasses to my collection.

Just making sure, you know you have to choose a base class first. In order to choose a fighter subclass for example, the fighter needs to be level 3.

Haha! Thanks. It wasn't the level requirement, but you pointed me in the right direction. I had assumed it was a certain base class and it was a different one! LOL. Feel pretty silly for not checking that! Thanks again for your help!
