Why does my chemistry recipe not work?

The Minecraft Education Edition involves chemistry, allowing you to create different chemicals.

Here is a PDF listing all the different things you can make with Chemistry. I used a Mercuric Chloride recipe to create a Red Torch. But it didn’t work.

I used Tungsten instead and it somehow works, creating a Green Torch! But all I did was use different chemicals! Why does the Green Torch recipe work but not the Red Torch?

I’m on Minecraft for Nintendo Switch, 1.16.1.
