Overview:
Customers may request to modify a profile called Package License Manager. This request deactivates record types. This profile is invisible to anyone other than Salesforce.
Root Cause:
Package License Manager is a standard Salesforce profile. Customers may want to disable the record types on that profile because record types can be seen when creating views.
Solution:
Open a case with Salesforce.com (SFDC) to deactivate the record types. Or, a link is sent to the user to point to where the profile is visible to admins.
