I’ve tried already the phantom scrip but maybe that’s not the problem
You seem to have two sets of testing here: one set of words with the directions English - Spanish and another set with English - English. So it isn’t really surprising that you can’t put all of these in one course.
I would split this content up into two separate courses: advanced English (with the English definitions of English words) and another one that tests the Spanish - English translations.
I don’t think this is a bug, it’s just too many testing directions and too many different kinds of input for one course.
