Since there's no more crucible tokens change the rank up engram back to current level.
Basically title says it all, but to clarify, the crucible rank up engrams were recently changed to drop around 20 levels below your current level so that people couldn't bypass the power grind by turning in a crapload of tokens. Now crucible tokens have been removed entirely but the rank up engrams are still dropping way below current level. This seems pretty ridiculous and unrewarding given that people can't abuse the token system to rank up anymore.
