I keep adding things to my homewbrew collection but they don't appear in the character builder. In Character Preferences I have Homebrew content turned on but it still doesn't show races, subclasses, or anything from homebrew in character builder. What can I do to add races and subclasses from homebrew on to my D&D characters?

Are you sure that “homebrew content” has been enabled? The toggle next to it needs to be to the right (red).

Also, it can sometimes take a little while for this stuff to populate the character creator.
