We show that [Lemma 3.3, p. 538] which was introduced in [1] is incorrect in general, by giving counter examples. Consequently, [Proposition 3.2, p. 539] is also incorrect. Moreover, the correction form of the incorrect results in [1] is presented. Keywords: Rough set, Covering, Lower and upper approximations, MSC: 54A05, 03E20, 54G2
