Rylak Metalhead’s Deathrattle not working as it should?

Hi guys, is Rylak Metalhead’s Deathrattle working incorrectly or am I just bad at math? It seems to me that scaling gems via Rylak Metalhead was bugged. I think I’ve received twice the buffs I was supposed to in my last game in HS Battlegrounds (final comp was Quillboars).
