Clearly the issue is that not all the elements of the interlinear are taking on the "contents" color specified in the theme. Interestingly, the original language texts do, but the English and Spanish texts do not. Certain "grammatical" items do (eg Lemma, Lemma Transliterated) but others do not (Gloss, Tag, etc.)
I've attached a screen shot using a custom set of colors that make it easy to see the items not changing color--and thus disappearing when Enoch tries to use them with his black background.
Enoch, for the time being you might see if you tolerate one of the existing themes or creating a new custom theme that doesn't bother your eyes but has a light enough background for the black elements to be seen.
