The stealth modifier is correct per the printed books; Tales from the Yawning Portal lists the Huge Giant Crab as a Huge Giant Crab with a series of specified changes. None of those changes modify the Stealth bonus.
Giant Crab (per the monster manual) has a +4 bonus to stealth.
Please double check the Stealth value for the Huge Giant Crab. It currently shows a +4, and I believe it should be a +5 (dex is +2, prof is +3).
