Waffle recipe calls for 300g of butter and 50g of yeast which seems excessive.

I'm checking out this Belgian Liege Waffle recipe(scroll down and click the liege recipe)
And it calls for 300 grams of butter and 50 grams, "one package" if yeast.
I didn't really do the math, but it looks like the recipe wants the dough to be nearly a quarter butter which seems excessive.
It also calls for "one package" of yeast which is 7 grams, but it also says 50 grams.
Am I reading something wrong or is the recipe messed up?
