Advice on the general case: a lot of country of citizenship properties, especially ones created early, were a bit slapdash and there's a lot of edge cases which get smoothed over. So don't assume they're gospel truth (or necessarily worth "disputing" rather than correcing) to begin with just because they've been there a while :-)

In this case, it looks like it was imported by inference from a Wikipedia category which implied nationality (eg "English writers") but may have been populated on the basis of residency or activity rather than official nationality; a lot of others got inferred from birth place, "born in London so British". Both of these are reasonable assumptions in about 99% of cases, but the 1% is a problem...
