Legendary Collector not incrementing

[Squidgeididdly.2930]

I have crafted five legendary items and put them on a character, but my Legendary Collector achievement has not incremented to reflect this.

I have crafted and placed onto a character the following:

* Astralaria

* Ad Infinitum

* Aurora

* Perfected Envoy Light Armour set

* Slumbering Transcendence 

My Legendary Collector Achievement has recorded only 3 legendaries.

 

I couldn't figure out how to upload images so here is a link to an imgur album of me mousing over my legendaries on my character.

"Bind 5 unique legendary weapons or trinkets."

1. Astralaria
2. Ad Infinitum
3. Aurora

That's my guess as PVP/WvW are usually an afterthought for these type of achievements.

I think that's the case, I don't remember it incrementing after making my PvE legendary armour either, but I definitely noticed it after Sl. Transcendence.
So I'm guessing that Vision will count, but Conflux won't, and perhaps neither of the other armour sets will count.

Perhaps the issue is that it's looking for Transcendence and I only have the Slumbering version.
And with the armour, it's six items so the cheev struggles to see all six together as one legendary?

 

these are my guesses

There's a separate achievement for PvE legendary armor
