Why is druid circle of the moon not available if it's in the dnd beyond compendium?

Quote from NoriTheHermit >>

Has this every been sorted (circle of the moon / druids)?
If no, where exactly can it be purchased from the marketplace?

 What do you mean by sorted? Moon druid has been available to purchase via the Player's Handbook for several years now

found it!

Players Handbook

Where can I find it in the market place? I’m struggling a bit 

players handbook, if you want just the subclass scroll down a bit to the section for individual purchases

This is still an ongoing problem because I own the players handbook and it is not showing the circle of the moon for myself or my sister who also owns the Players handbook.  It has circle of the land but no circle of the moon in the drop down menu for a 3rd lvl druid.

 Which players handbook do you own? If it's the 2014 one, you need to turn on legacy in the character builder and pick the legacy druid class. 

same for me
