Circle Spells for Circle of the Moon druid don't seem to be showing the source

In the Spells tab, the source from which you got the spell should appear underneath the spell.  It used to identify the spells that came from the Circle of the Moon spell list, now they just say "druid".

Looking at my Moon Druid, it shows the Message cantrip they got from the Primal Order class feature as coming from "Primal Order", but Starry Wisp (which came from the Circle feature) just as "druid".  This is the same for all of the Circle spells; spells from other sources like magic items or feats show where they came from, but all of the Moon Circle spells through Mass Cure Wounds appear as normally-prepared druid spells.  

This is specific to the Spells tab in the character sheet; if you go into Manage Spells, it still shows the Circle Spells as "always prepared", so DDB knows they're coming from the feature, it's just not displaying the source properly.

Compare this to the spell list of a Circle of the Land druid; I built a High Elf land druid, just to see what their spells would look like, and the cantrip they got from the circle feature (fire bolt from the Arid Land feature), specifically says "Circle of the Land Spells".

Given that the spells from other Druid Circles still indicate where they came from, I think this is probably a bug with the Circle of the Moon spells.  It's especially irksome because Moon Circle spells can be cast from Wild Shape, so it's actually relevant to be able to see which ones came from the Circle spells feature at a glance.

Can you set your character's privacy to public and share the link please?

You can see the issue on this one where I was able to reproduce it: https://www.dndbeyond.com/characters/170518854

This used to work correctly, and the Circle Spells even included a specific note about being able to cast them while in Wild Shape, which they no longer do.

wagnarokkr's linked character shows the same thing I'm seeing, and is a good representation of the issue (especially since it was newly-created, so we know it's reflective of the current state), but since you asked, here's a link to the character in question:

 Definitely reproduceable, though, as wagnarokkr showed.  I also quick-built a new druid character to double-check what I was seeing.  Not sure if this is an issue for any other subclass-granted spells (aside from the Land Druid, which I confirmed was working as-expected).  It's likely that, if it's an issue elsewhere, it might go unnoticed since there's less of a need to know what feature any given spell came from when there aren't mechanics that are directly impacted by it.  I'm thinking something like Aberrant Sorcerer, who needs to know if their spells can be cast with the Psionic Spells feature (just checked, this one seems to work).
