OT355 Metadata title differs from other book studies

I had tried using the Courses tool filter box (both ot355 and 355) to find the Isaiah book study, with no luck.

Searching for book study showed why OT355 didn't show up in earlier results. Unlike the other book studies, the course number doesn't appear in its Courses tool title. 

Could its metadata please be updated to make this course easier to find in the future by course number? Thank you!
