There is a rule for it actually in https://bendhealth.genesis-unlimited.com/wp-content/plugins/wpbakery-hexagon-masonry-gallery/assets/vc_hexagon_gallery_pro.css?ver=5.8:

@media (max-width: 900px) and (min-width:601px) { /* <- 3-2  mashexagonProagons per row */
  #mashexagonProGrid{
    padding-bottom: 7.4%;
    font-size: 14px;
  }
  .mashexagonPro {
    width: 33.333%; /* = 100 / 3 */
  }
  .mashexagonPro:nth-child(5n+4){ /* first mashexagonProagon of even rows */
    margin-left:16.666%;  /* = width of .mashexagonPro / 2  to indent even rows */
  }
}

You need to change screen size for it like this:

@media (min-width:1201px) { /* = 100 / 3 */
  #mashexagonProGrid{
    padding-bottom: 7.4%;
    font-size: 14px;
  }
  .mashexagonPro {
    width: 33.333%; /* = 100 / 3 */
  }
  .mashexagonPro:nth-child(5n+4){ /* first mashexagonProagon of even rows */
    margin-left:16.666%;  /* = width of .mashexagonPro / 2  to indent even rows */
  }
}

I hope this works for you.
