This won't be any help, but I get the study bar in the first old testament manual. Which institute manual were you trying? I also get it in the current issue of the Liahona magazine. My understanding is that the problem manifests itself from page to page (one chapter will have it, the next won't, then the one after that will), so we may need actual pages. (Or it may be that it's all fixed, but some folks need to do the whole bit about emptying cache and deleting cookies - I don't know.)
Sorry I can't help beyond the fact that some pages in those manuals/magazines are working for me.
