I encountered this earlier. It's the 'Facsimile Editions' presented on Logos.com as 'Enhanced for Logos' branding, but presenting a blank page (in this case, North-Semitic Inscriptions' below). But it was Pliny the Elder I was wanting (Essenes), and being Logosian-smart, I thought to check if they fixed the presentation. It does present the Overview thumbnails; now to be able to actually read them.
Below, is after selecting a page from the Overview thumbnails. And I don't get it. Mac M1; latest Verbum.

Pliny the Elder's blank pages are not unlike his place in the Lexham Bible Dictionary (a single sentence worth). The Younger got more.
"Pliny the Elder (ad 23/24–79). A Roman author and philosopher who is most well-known for his contributions to the study of natural philosophy."
And for any geographers passing by, don't forget Strabo (even if Pliny is having trouble):
Geographers of the Roman Era (26 vols.) (probably DOA in Logos, but maybe eventually)
And to whet your appetite on Strabo (an older discussion):
