:07amThe only thing I see that's wrong is the "b" lead width has no tolerance and it should, but that would not cause the error but it will cause a bad Land Pattern Footprint

. How much pad is trimmed is difficult to list in the "Warning" box. Simply make the component lead width maximum tolerance a smaller number until the error message goes away.
