Hey, all. I was recently trying to make a Jellicent for a UU team, and I noticed something peculiar while doing so. I tried to change the gender of my Jellicent from Male to Female, and oddly enough, the gender stuck to Male while being previewed. So, being curious as I was, I tested it out with its pre-evolved form, Frillish, and yet another Pokemon that I know has a different look when it comes to genders; Meowstic. Surely enough, the menu sprites stayed the same for Frillish, but as for Meowstic, the menu sprite at the top right did change when I made it Female, and the form ALSO changed to Female. I've provided screenshots below to show you exactly what I mean:
Male Frillish - http://prntscr.com/69ual6
Female Frillish - http://prntscr.com/69ub26
Male Jellicent - http://prntscr.com/69ubcs
Female Jellicent - http://prntscr.com/69ubly
Male Meowstic - http://prntscr.com/69ubx6
Female Meowstic - http://prntscr.com/69uc3k
As you can see, next to "reroll," the gender icon DOES change. The fact of the matter is that the menu sprite at the top right doesn't, and neither does the form itself in the drop-down menu next to its level of Friendship. Another thing that I should mention, is that when I injected all six of these Pokemon into my game, their genders had all changed accordingly; the problem lies within the preview of the Pokemon in PKHeX. A quick fix, but it needed to be shared. I couldn't find a post regarding this bug, but if there already was, please let me know. Thanks!
