Whether you work on Server/Datacenter or Cloud you will only find one Predefined Layout. This Layout cannot be deleted but it can be edited.
When migrating from Server/Datacenter to Cloud, the Predefined Layout information will be carried over to Cloud only in the first migration, does not matter if it is later renamed. This means that if you have done several migrations, and during that period the predefined layout was modified in Server/Data Center, those changes will not be applied in the predefined layout on Cloud.
