This seems to be a bug but I may be overlooking something. If I right-click δοῦλοι in Eph 6:5 from NA27 (tab shown unselected on the right side of the image below), go to Lemma, and select Bible Word Study, I get the Word Study shown on the left in the image below. But if I run the exegetical guide and click δοῦλος from there, I get the Word Study on the right. It looks like it's trying to run a Word Study on the same word, but it gives very different results.
