Default OneNote folders in OneDrive for Business.

When I look into my OneDrive for Business, I can see some OneNote folders which seems to have been created automatically - may be the sync process?

The folders look like:

1. Vinod@ParentCompany

2. Vinod@OneDrive-ParentCompany

3. Vinod@Company2 - where I am a guest user.

Any idea how these are getting created and can they be controlled?
