Evolution new mail notification inconsistent

I am using Evolution 2.3.2 and find the new mail notification in the Top Panel to be inconsistent. My setup is a 15" laptop connected to a docking station and a larger external monitor (Screen1) configured with Separate X and Xinerama, First, I do not care that the Top Panel is rendered on both Screen0 and Screen1. But what I see is that the Evolution new email notifications are only updated on Screen1 (I saw some older post elsewhere that indicated an updated PPA for Evolution included a fix for notifications, but that had no impact here.)

So I would like to see the notification updated correctly on Screen0. If there is a way to have the new email notification updated correctly on both Screen0 and Screen1, then I would appreciate any information in that regard.

Coincidentally, I see the opposite behavior for Evolution appointment notifications. The appointment notification indicator is raised on Screen0, where I would expect, and prefer, to see it I would rather see the new mail alert here as well.
