I am using Logos 8.7.0.0042 on Windows 10 Home.
However I noticed this happening in previous versions of Logos 8.
Workflow resulting in issue
When preparing a sermon I use the following workflow:
1) I duplicate a "template" Notebook on documents.logos.com.
2) In Logos/Notes I search for the duplicated Notebook and then rename it to reflect the text I am working on. In this example the duplicate Notebook is entitled "Sermon prep - template (2)", and I have renamed it to "Sermon prep - Luke 14:7-14".
3) Logos renames the Notebook correctly and opens it.

4) However, the Notes tab title does not rename to match.

5) This means that when you want to create a note from e.g. a Bible, the Notebook name is still the old one, rather than the renamed title.

The good news is that when you exit Logos 8 and restart it, the table title refreshes to the correct one, so it's only a temporary "bug".
Please let me know if you need further information.
Blessings,
Michael
