The list of them I've found so far are Arms of Hadar, Armor of Agathys, Hunger of Hadar, and Summon Aberration. All 4 of them are "Core Rules". If you link them like Armor of Agathys it works fine, but if you actually grant access to the spell either through adding it to their spell list or granting it as an always prepared spell, it refuses to let you, saying "This homebrew Subclass has data mapped to it that is licensed content or private homebrew. This typically occurs when licensed or private homebrew spells are linked to the Subclass." I need to be able to publish this as I'm making it for someone that is not one of my players.
In case you are thinking I must've had something else causing it, no, I couldn't figure out what was causing the error so I removed all links and granted spells in a subclass and added them back one by one, checking to see if I could publish each time, and these 4 caused the error to occur.
I haven't tested to see if it's the same on not subclasses.
The restriction isn't about whether the spells are in the Core Rules; it's about whether they're in the free Basic Rules product, which none of those spells are.
"Core Rules" refers to the Player's Handbook, Dungeon Master's Guide, and Monster Manual. All those spells are in the Player's Handbook, so they do count as "Core Rules". But they're not in the free Basic Rules, so you can't add them to published homebrew subclasses.
Also, you can share the homebrew with a specific person through a separate campaign. They'll be able to add it to their character. and keep it when they move it elsewhere. I'm not sure if they'll be able to add it to their collection if they have a Hero or Master subscription.
Then it should clearly say that. There's no way to tell in the process of homebrewing or even looking at the spell's page to determine that it's Basic Rules. The only way to do so is to go into the basic rules and check. In homebrewing it just says "Core Rules". On the spells page it says "Player's Handbook" regardless of if it's from Basic Rules.
As an example, here's a bunch of spells that have no way of telling whether or not they are "Basic Rules" without going into the basic rules spell description.

I mean, you're right, it absolutely should be labeled much more clearly. I don't disagree.
