Hi @Esteban DeVault,
To narrow down the problem, we need more information.
SCCM console -> Software Library -> Software Updates -> right-click Software update Groups and Import Software Updates Group.
1, How did you achieve these steps? I can't find the option Import Software Updates Group.
2, We can import the software update by following way:

Note: Microsoft provides third-party contact information to help you understand the problem. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.
3, When did you get this error? Please help upload some screenshot for our reference. We may need to confirm that if your SCCM server needs install this update, or the package you are importing is missing this update?
Looking forward to your feedback.
Best regards
