I have a Collections tab as part of my Layout and though I do not see an Unnamed Collection when I first open the tab after a restart, one has been created. In this instance I had previously created an Unnamed one for testing purposes ie. non-blank!
Example (see below):
- Select Commentaries in Collections tab
- close Tab by selecting LGNTI
- restart L4
- select Collections tab (Commentaries is displayed)
- select Open menu and find Unnamed Collection(s).
