There are four studies whose citations have not yet been imported.
These are the citations for studies

The reason is that the citation dump file you sent specifies citation types "Thesis", "Thesis", "Electronic Source", and "Conference Proceedings", respectively. But our data model has (at present) only citations of types "Journal Article", "Book", and "Book Section". Rutger quite properly had the citation data importer ignore citations of unknown types.
BP says:
My sense is that "Thesis" and "Electronic Source" can be squeezed into "Book"; and "Conference Proceedings" can be squeezed into "Book Section" -- we can do that for now just to accommodate these cases. But a future "new feature" might be to expand the repertoire of our publication categories -- but definitely only for down the road.
