Kepub option no longer comes up with new Calibre version

Also posted this in the Calibre forum, but wanted to find out if anyone else here in the Kobo forum has had this issue.

I upgraded Calibre to the latest version (3.43) and I no longer have the option to convert ebooks to kepub. My main readers are Kobo, so this is not a good development. Has anyone else encountered this with the latest version?

I do have the Kobo Utilities plugin, which has worked fine forever.
