In the clause search my Greek New Testament is not available. This has been true in several Beta updates.
You should have the resource Greek New Testament SBL Edition + (in Help >> About Logos) you should see the dataset DB:CLAUSES-LGNTISBL listed under Clause Search in the scrolling panel.
If missing then try the command Update resources
It is not listed in the dataset but I own the SBL edition and it was working with the clause search.
Here is a screen shot.
I am able to reproduce this issue and will report it to Development.
Did you try entering "update resources" into the command bar in the main window, to force a check for missing resources and data sets?
I tried "Update resources" and that did the trick. Thanks Bradley! I still don't know how I lost SBL data set in the first place but now it is working.
