Pressbooks-book-2.9.1.zip

Problem is that I still get an error in Themes stating that the Pressbooks-book needs to be upgraded even though it is already been processed:

Observing other themes, they have changelog matching current version listed in themes (e.g., Jacobs):

Changelog

1.2.1

Whereas McLuhan is:

Changelog

2.9.0

Donham theme has no changelog. In my oberservations - all the Themes in the list that display the correct current version have the current changelog in the readme.md
Only Donham and McLuhan seem to be inconsistent.

Ideas?
