NetGalley download don't have double-page view

I downloaded some comics from Netgalley. Unfortunately, the double-page view option is greyed out on ADE and this makes it difficult to read some sections. Can anyone advise how to enable double-page views? I have macOS 10.15.5 and digital editions 4.5. 

 

Would it also be possible to include a double-page view option on the iPad version or ADE? The screen is large enough to accommodate this.

I guess no one can help. Very frustrating.
