This is with Logos 32.1 on Windows 11
As per the screenshot below when looking at the Factbook entry for Edler, the Referred to As -> Greek entry for ἄρχων just all three results - all in the apocrypha.
But a search for that lemma translated as ruler shows 43 results - many of which are in the New Testament.
Is there a problem in how this is working?
