Maeva is also used as a masculine name in Tahitian and French. However, it's more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine". Some evidence for this is that Maeva is also used as a name element in unisex and masculine Tahitian names, such as Maevarau.Source: https://forebears.io/x/forenames/maeva
