In this paper, we point out that the proof of Theorem 2.4(5), Proposition 2.6(1) and Proposition 2.8(1) in the paper titled ”On (L,M)-fuzzy convex structures” (Filomat 33(13): 4151-4163, 2019) are not true in general. Then, we give three correct proofs of these results

Keywords: (L,M)-fuzzy convex structure, L-fuzzy hull operator, (L,M)-fuzzy convexity preserving function
