Deathstalker Rexxar, Zombeast doesn't have keyword on the card (but it did have the effect on board)

Played Hunter in wild, played Rexxar and crafted a beast. I picked “Scavenging Hyena” and the new “Circus Amalgam”. Circus Amalgam have the keyword Taunt but it didn’t have it on the zombeast card.

However, when I played the Zombeast on the board it did have Taunt. My guess is that the Amalgam card have a emphasized text which made a bug or soo. But I could be wrong here. Eatherway, I needed a taunt minion soo it was tricky to know if it would have taunt or not if I played it.
