Whenever I look up the stats for a course on LingQ only the new words get highlighted. If I were to look at an individual lesson. The yellow progress bar (LingQs) and the white progress bar (Known Words) do show up, however never in courses.
First picture is the course progress bar.
Second picture is the lesson progress bar.
The white bar isn’t super distinguishable but it’s present. If anyone can fix this that would be nice!
