When pressing the "Check All" button, the "Shiny" checkbox and any empty boxes in the Viewed categories are never checked. In fact, if the "Shiny" checkbox is already checked, it will be unchecked, which I feel is counterintuitive to "Checking All".
Also, the "Check All" button seems to randomly switch the Display gender between Male and Female, which I assume is unintended behavior.
There are not enough spaces in the Seen/Obtained/Heard Of/Viewed categories to fit all of the Alcremie formes.
