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.

1.16.1 is quite an outdated version. There were many minor fixes and improvements over the times. The current version is 1.16.20.

Try updating to the latest version and see if it works.
