Importing multi-page PDFs into InDesign v17.2 not working

We are using InDesign v17.2 on our three Windows PCs and when attempting to import a mult-page PDF into a document that is ready to receive the pages in the correct order for imposition with 'Show Import Options' checked and 'All pages' checked, it only imports the previewed page.

It's as though the facility has somehow bugged on the last update, as this is only a recent issue.

Has anyone else experienced this, as all our versions of InDesign are also having this problem.

I have used the Javascript version of the import, but it's relatively basic, and doesn't fulfil our requirement.

Any advice would be appreciated, or maybe have to wait until another update.
