Query: Samba is wrong (among others things apparently)

As two other reviewers checking only one star, I have found another wrong notation. In the samba section (named batucada here, which just means "bunch of percussionists"), the part usually played by a medium bass drum is reversed. It should be quarter rest, two 8th notes, quarter rest, 16th-8th-16th. Instead it begins on quarter rest, then 16th-8th-16th. This is one of the first things you learn in a samba group... This reveals not even a basic knowledge of the style, and made me wonder wether the other styles were not wrong, too...
