/gflex/ and GFLEX are just names. They're no more "official" than any of the other platoons on the list. There's a limit to how many members one platoon can hold, so it's only natural that several were founded. Especially at the beginning.
All that being said, both are by my reckoning decent platoons. I think we're full right now but you could reach out to either if you really want in. (Or just join one of the many other platoons.)
