I created a sub class, however it is not showing up under my druid I even have it publicly published. I double checked that its base class is druid. I even went through and added others homebrew to see if the subclass would appear, nothing is. I'm just getting the Statement of

"You currently have no available optional class features for this class

Also to notate I'm able to add the homebrew race I saved. But subclass is the one refusing to appear

An optional class feature is not a subclass.

I understand but I'm not finding any subclasses.

I've looked in the main class area for the subclass too and it only allows to select basic druid and does not give any subclass options

Druids pick a subclass when they reach level 2.

The character IS level 2 and it's still not showing up that's the issue I'm having. I am unable to add the subclass

Take a screenshot of you navigating to the Druid Circle feature of your class where you are unable to select anything.

I finally found it and it became accessable

A Druid subclass is called it’s “Circle,” you select it’s subclass from that dropdown:

The character may be 2nd level, but if you didn’t specifically level-up the Druid class then you are still only a 1st-level Druid. The system does not automatically apply level-ups to classes because it doesn’t know if you want to multiclass or not.

Sorry to bother but im having the exact same issue, I made myself a private subclass for druid and leveled it up to 2 with the choice of which circle i want but it wont show the subclass I made for it (Yes homebrew is on)
