Export to PDF always exports last sheet not selected


Recently Export to PDF seems to have started ignoring sheet selection,
exporting only the last sheet instead (which is a summary sheet I added recently… I might try making a copy without it)

Can confirm it works if I delete the summary sheet, which has references to cells in the other sheets

Has anyone seen this?
