No update on lodstone (guildmarks)

A couple of days ago i went to blacksmith guild to buy "Fletchery training".
Usually this will get you a milestone under history on lodstone.
Now i have waited for a couple of days but nothing.
I have completed a couple of quest after this and they all appeared under history but not my "fletchery training".
I have also checked under attributs==> key items and there it is, so i have it in game.
Can it be a bug or maybe it will appear in another couple of days?
Any ideas?

I'm almost sure the books you buy for DoH classes don't appear on Lodestone. I suppose it's because they're not skills or traits, but key items.

I dont think they have ever appeared as an achievment in history either.

Yes, you are right. Thankyou for your answer^^
