Yeah it looks like the Union flag is next to Gabon. I think the country code is GB so it’s next to GA even though the name is United Kingdom. That might be what’s throwing people.

The two US flag emojis are actually different Unicode emojis.

The first is 🇺🇲 ‘U+1F1FA U+1F1F2’ and is for ‘U.S. Outlying Islands’.

The second is 🇺🇸 ‘U+1F1FA U+1F1F8’ and is for ‘United States’.

No malice, no bad code, no bugs or typos, this is just expected behaviour.
