Bah. Q258045
Looks like it's picking them up now - perhaps a caching issue? The queries sometimes take a few minutes to regenerate their results if they've been run recently.
Hmm. Still only Mimma Zavoli turning up. Never mind. I have another one for you. Sri Lanka shows as ?office=President of Sri Lanka in Wikidata:EveryPolitician/Report:P39/Q2285706 but as ?office=Prime Minister of Sri Lanka in Wikidata:EveryPolitician/Report:P1313/P1308.
Scratch that. Wikidata:EveryPolitician/Report:P39/Q2285706 is now missing Sri Lanka, despite Q983402 seeming to have the data required to drive the Q228 report. Hey ho. I'll maybe slow down and try to fathom the diffs between the Q2285706 and P1313 reports...
Sri Lanka was missing because Prime Minister of Sri Lanka (Q1758894) didn't have its applies to territorial jurisdiction (P1001) set. I've fixed that, and also improved the documentation here to suggest people check for that one.
