Ive always found kaplans textbooks to be excellent and i qualified using their materials so they worked for me. Im not excusing errors in the books and do believe that they should deal with them appropriatey.
However tens of thousands of people have managed to pass exams using textbooks with a lot of errors. The fact that you have identified them is good and shows that you have an eye for detail. In the workplace you will also have to deal with this. We could be given folder upon folder of information that has incomplete, inaccurate and useless information that we need to sift through to use in a meaningfull way. But i do sympathise it is difficult to learn when you come accross errors all the time. Good luck
