Are you selecting the files for import “from files” or “from document library”?
I can get a list view with either one.
If working on iPad and selecting from the MarginNote Document Library, try clicking-then-dragging the list downward as though to refresh it, then look for the list icon on the upper right (first image below).
If this is iPad, the list toggle should already show, since Recent/Names categories are shown. So I think it is on Mac (the system should always be mentioned).
