Editionalised subnav not showing for some articles

[cemms1]

Some US sport articles show the US subnav e.g. https://www.theguardian.com/football/2023/oct/19/lionel-messi-mls-apple-tv-documentary-beckham

Others show the UK subnav e.g. https://www.theguardian.com/football/2023/nov/15/premier-league-nfl-gambling-suspension-tonali-toney

The US team would prefer to show the soccer subnav rather than the football one and want to understand how they can make this happen
