With the release of BeerSmith 3, the maximum %ABV for a recipe was established by the yeast strain in the recipe. If no yeast is stated, it defaults to 10%. This had been requested by users years back and finally put into the program.
I should have also added that I would double check the properties in BeerSmith for the yeast against the manufacturer specifications. In many cases, these ingredients were added years ago and have not been updated to match manufacturer updates. That actually applies to all the ingredients, not just the yeast.
