Sorcerer Subclasses Not Showing

I have most of the pre-2024 book purchased on D&DBeyond and I am trying to build a Sorcerer but not all of the subclasses are showing up as options.  I am specifically trying to the Abberent Mind subclass from Tasha's (which I definitely own because I am using a Psi Warrior Fighter in a different game.)

Does anyone know of a reason why this could be an issue?

I looked at the "Expanded Rules" and it is checked.  I currently have her as a "Shadow Magic" sorcerer from Xanathar's, so I assume that my other content is working just fine.  Like I mentioned originally, I have a different character that is using a subclass from Tasha's, so I really don't understand why those options are not showing for this character.

I finally found it.  I had to delete my class selection and re-select the class to gain access to the 2014 version.  Thank you for your help.

I just bought the 2024 PHB and the subclasses still aren't showing up. Any ideas?

They weren't! Thank you!
