Missing base appearence on aquired Legion Artifacts

I am missing the base purple color on my Paladins Vindicator’s Bulwark. By missing a it had the lock icon over it as If I never acquired it. Yet, I have the last two color options unlocked and 50% progress through the second one.

Anyone know what is going on here.

Check your achievements, there could be a requirement you are missing, some of them are tied to world quests, dungeons and pvp
