Guild Wars 2

I had all grawl and krait weapons, so I just needed the collection unlocker item. So I went and farmed the two of them. Both got completed 3/3 once I got the item.

Then I check my achievement points and notice they only gave me one point each, when they should have given me 3 instead.

Is this a bug? Did they give me the other 2 points before, without me noticing because the collection was hidden?

Thanks in advance.

Edit: Same for hylek.

You got the other 2 AP the first time you logged in after september 9th.
