Hi - I’ve been playing Wow for a while (since 2008) and have leveled all professions up at least to Pandaria (if not to max level) over the past 17 years, but…I’m not understanding something on my Engineer (Gnomish) and would like some wisdom from you all.
Let me explain: On this toon (my main) I’ve leveled her Alchemy (Transmutation) to max for each xpac. I’m also a ‘completion-ist’ and like to obtain all recipes/patters/schematics/etc., and as I do, I see my “unlearned” list decrease until there’s only a handful of unlearned recipes. I love that my unlearned recipes list is small and uncluttered. Sadly, this is NOT the case on my Engineer unlearned list 
When I look at my Gnomish Engineer, I see a long list of Classic schematics (205 level) not yet learned. (I’m only talking about Classic for this post). As I scan down the list, it appears that some are Goblin. Well, I’ve chosen Gnomish many, many years ago, and I’ve no interest in changing it.
Is there some way that I can get those “unlearned” Goblin engineering schematics WHICH ARE CURRENTLY UNATTAINABLE TO ME AS A GNOMISH ENGINEER to go away/stop being shown under “unlearned”? I’m asking because I’m working on completing all unlearned engineering that is available to me, and these Goblin schematics are just clutter on my screen and I really dislike them there, since I’ll never be able to obtain them.
