Hey just wanna hop in and say I was having this issue too.
I have a fix though.
make sure the last meditation point you were in ISNT the one in the basement of Pyloons.
go to the one outside of town and then buy all the merchandise. Achievement should pop then.
for some reason the meditation point in Pyloons glitches things like this among other things.
Please tell me there is a way to fix this dude... only other save i have is the one where i collected 22/100 priorite and i dont want to collect all this * again, i would also have to go to some annoying locations i hate to get it ......
This worked for me:

Just open your skill tree and pop does the achievement.
