Tier sets missing... ? Buying mythic set does not give all other sets anymore?

I started Legion remix with a Death Knight and i managed to buy all the tier sets (nighthold) last week for all classes.

And as Blizz has stated, once you buy the Mythic version, all other versions (heroic, normal and lfr) will also exist in your completed sets. And its true, with the death night i have them all after i bought the mythic version.

*please note that you can only buy the mythic version, all other version were removed pror to remix legion start.

HOWEVER, i log into my other alts, shaman, priest, paladin, etc…and they only have the mythic set, not the others.

Why?
I thought Blizz said that once you have the Mythic set you have all the sets.
So what gives?

It has to be a bug. I bought all of them in phase 1 and I have all the set unlocked.

So i checked all the classes.
Only the Shaman, Paladin and Warlock are missing tiers sets (heroic, normal and lfr).

They do have the mythic set..

Also, creating new toons does not solve the issue.

Same issue here. I had the hunter raid set “Eagletalon Battlegear” from Nighthold Mythic, Heroic and Normal and a few pieces from LFR before remix. With Nighthold raid now released in Remix, the rest of the LFR set didnt get unlocked. I had to buy the ensemble from the remix vendor, even thought it said “already known”, to unlock the rest of the LFR set.
