It's probably because of the new version, although it specifically mentions that admins should not be affected...
Notice: Please review these important changes, some of which require user action:
Compliance score calculation changes - your compliance score now includes Microsoft-managed control scores.
Set permissions for all users – all users must be assigned a provisioned role by "10/30/2019" in order to maintain access to Compliance Manager; there will no longer be a default Guest Access role. Admins may set permissions by visiting the Admin settings in Compliance Manager and assigning a role to all users. Admins are not impacted by this change; they will continue to have access.
Accept mandatory updates – important template updates are coming that will impact Compliance Score calculation and functionality. On your Templates dashboard, you will see alerts noted with a triangle icon—we strongly suggest you select Update to every alert attached to your templates to ensure your score is accurately calculated. You should also accept all updates to Assessments to ensure proper functionality.
You can open a support case I suppose.
