4.2 Beta 1 Sentence Diagramming Bug

When inserting a new passage into a sentence diagram (NA27, text flow, no alternate line) from John 10:22-42, ἦν is sometimes not displaying correctly. It lacks the eta (η), smooth breathing( ̓ ), and accent ( ͂ ), so that all that displays is the nu (ν). This happens in both 10:22 and 10:41, though it displays correctly in 10:40.

ην is the last word in both verse 22 and 41; this seems to be the problem. I tried inserting John 1:15, which contains ην twice, once in the middle, once as the last word, and it displays correctly in the middle and incorrectly at the end.

Update - The diagram also drops an epsilon and smooth breathing from vs. 29 (ἐστιν) and vs. 30 (ἐσμεν)
