DTPO- Yosemite Import Mail not working?

Anyone else finding Blank/plain folders trying to import Mail.app messages into 2.7.7. in Yosemite?

How did you try to import the messages and did you install the plugin for Apple Mail?

Icon in menu bar I added via customize.
Yes plugin installed. The window comes up but the folders are generic white with nothing inside (sub folders as you see in Mav.
Using only Mail.app connected to iCloud and Exchange.

The next maintenance release will improve the compatibility of File > Import > Email… to Yosemite’s Mail application. However, the command “Add to DEVONthink Pro Office” of Apple Mail should be already compatible to Yosemite.

Using Mail’s menu does indeed work. Thanks. I do not use that normally.
