When the Bible Word Study Guide displays, the "Lemma" section appears to list the principal parts (tense forms) of the verb. In a spot check of several lemmas, it seems that the last principal part, which should list an aorist passive form, lists instead the aorist active. (See screen shot)
λύω, πιστεύω, λαμβάνω, for instance, all show this way, with the aorist active form in place of the aorist passive.
