Incomplete Padfoot recipe

In ingame recipe for Padfoot, the last step (distill) is missing. I am playing the game with Czech texts, v 1.9.1, PC, no mods (only slightly tuned user.cfg for nicer graphics).
I was wondering why I get only 2 elixirs instead of three and then I googled that there should be distillation at the end. But it is missing in the ingame recipe.
