As most Pokemon GO trainers know, the Generation III Pokemon have been hidden deep inside Pokemon GO for quite some time.
Part of the Generation III Pokemon are the popular Legendary Pokemon duo Latias and Latios. According to dataminers, Niantic has given Latias a 100% male spawn rate, and Latios a 100% female spawn rate.
This is completely incorrect as Latias and Latios are female and male respectively in the anime and video games. Hopefully this error will be ratified soon, or it will be a huge disaster when Latias and Latios are out in the wild!
