Achievement - Flawless Victory

So, since the QOL update where there were new achievements posted (which I received when I logged in), there is a "Flawless Victory" achievement. This achievement states that you must win a TW by defeating all territories, which my guild has done on multiple occasions.. Is this only counting raids this side of the QOL or does it include prior wins and is just a bug?

Its a lot of guild coin/event coin to just be sitting there.. staring at me.. knowing my guild mates and I have achieved it!!
