If you had clicked on the links above, it would have shown you the one about Ibadaat, (folding arms, how many rakat etc.) There is no specific book by him that jots down which fiqh is wrong in which way, rather such clerifications are spread out throughout his work, and thus were later compiled into fiqh-e-Ahmadiyya.

Often a person, sometimes Ahmadi, sometimes not, would ask a question regarding fiqh and he would answer it which was then noted down a collection of 10 volumes known as Malfozat. Though the volumes of Malfoozat encompass much more than fiqh.
