Can't choose Hermit Background for my Druid?

I am rebuilding my 6th level dwarf druid character in DnDB, but his Hermit background is not an available choice in 5e core rules.  I have PH (2014) turned on, and the option is clearly in there. What am I missing?

Do you own the digital version of the Player's Handbook?

You can only use character options from books you have access to on D&D Beyond. Since the Hermit background isn't included in the free Basic Rules product that everyone has access to, you would need to own the book it comes from (the 2014/5e Player's Handbook) or have access to it through content sharing in a campaign.

If you're able to see the Player's Handbook content but not use in the character builder, it's because it's being shared with you in a campaign, but you're not making the character in that campaign.
