Had the same issue, this is the current workaround for it.

I’m having this issue with Rank 3 Nazjatar essence. I can’t even buy the essence from MOTHER on the exact character with Rank 3

Edit: Workaround that worked for me:

• When I just learned the Rank 3 Nazjatar essence (Essence A) it did not appear for alts.
• When I learned a new Rank 3 essence (Essence B) the previous Rank 3 Nazjatar essence (Essence A) now appeared for alts (but the new Rank 3 essence (B) did not).
• By learning another Rank 3 essence (Essence C), Essence B became available for alts (But, not Essence C)

TL;DR: Try learning a new R3 essence (not a duplicate) on the original character with the R3 essence you want to pass to alts to see if the previous ones now appear for alts

An easy Rank 3 Essence to get is the Crucible of Flame from the Investigating the Highlands quest from Kalecgos in the Chamber of the Heart. Your Heart of Azeroth needs to be level 60 to unlock it. As soon as my main learned another rank 3, the Ripple in Space Rank 3 became available to purchase.
