Importing MOBI & EPUB into Research Folder

Hi,
just out of curiosity, I tried to import ebooks into a Scrivener project today. I came to different results.

Kindle files [mobi] were imported correctly into the Research folder and converted to RTF files. :smiley:
EPub files, however, were not imported as text. Only a link to the file was placed in the Research folder.

Is this possibly an error? Or is the import function for EPUB just not implemented yet?

Many greetings
