Hi Community experts, please advise on the below:

After upgrading to 25R1 SU3, we observed new document classes (e.g., DISCO DOC, INVOICE, IPC DOC, IPC JSON, IPC REV, MM DOC) appearing in the Document Class basic data. These classes are visible to all end users. Does the upgrade add these classes? I would appreciate it if you could shed some light on this for better understanding.
