Why do liked pages not appear in profile sections?

I have just under 200 liked pages and I understand under some of the sections (e.g. films, TV programmes, etc.) on my profile they do not all fit in (e.g. Gumtree the company does not fit into any of those sections) but using a specific example - I've liked Fearne Cotton's page which is listed as a "Public Figure" - the same as Bill Gates, yet her page does not appear in the People section of the my likes on my profile.

This is the same for other pages which are listed as if they should appear under some of the liked sections but don't. Seems very random.

Any ideas on why this is the case?
