1. Install vocab list for A Grammar for Biblical Hebrew (Seow) from http://www.logos.com/training/vocabularylists for Logos 3 following instructions under step 5 on that page.
2. In Logos 4, type Import Word Lists in the command line.
3. Restart Logos 4.
4. Open the newly imported word list.
5. Click "Cards" to view as cards instead of grid.
6. Keep the default settings of Letter, and 10 Cards.
Result: Notice that on page 2, the left card in the 4th row is blank. BUG!

7. Click back on Grid to see why.

Notice that the Lemma column is blank for this word, while Display shows קֹ֫דֶשׁ. Notice that there's another word that also has a different value in the Display column than the Lemma column, and confirm (by clicking Cards again) that this word too displays the Lemma rather than the Display version:

Diagnosis: The Lemma column is being displayed on the Flashcards instead of the Display column.
Expect: Display column should be used. I should think that's what it's for. Display, eh?
Extra info: I still have Logos 3 on my machine but can't test to see how it handled this, because I cannot seem to find the Vocabulary Lists option under File Open, even though the .lbxvl file is in the right folder (My Documents\Libronix DLS\VocabularyLists).
