So I decided to create a custom interlinear for front-line text critical comparisons of the Versions... I started with the BHT, and added the MT-LXX interlinear, the DSS, and the SP. To test it, I went to a text for which I knew what the results should be, and discovered some discrepancies.
At Gen 2:2, the MT reads ויכל אלהים ביום השביעי But the LXX, the Peshitta, and the SP all read הששי. Yet the interlinear that I created has the SP reading השביעי along with the MT.
To ensure that I was not losing my mind, I added the BHS apparatus and the SP in parallel, and they confirmed what I was noticing—that the interlinear is rendering the reading of the SP incorrectly. Also, I noticed that ששי in the (parallel) SP was not cross-highlighting, yet the definite article does. (Please see images attached).
I don't know if these two problems are related. Is it possible that I just missed something? Or is this a bug?
