I can reproduce this and have filed a case.
As a workaround, choose a preferred Bible that has a Hebrew reverse interlinear (NET Bible does not).
Thanks a lot Bradley!
I did the workaround in a different way, my mother tongue is Finnish so I don't normally use reverse interlinears [A]
We've published a metadata update that should fix this problem; restarting the application should make it download.
