@Netgeo,
Rkomar has right,all E-ink devices have a ghosting effect. Some people prefer a light ghosting effect than a full refresh of the page. Normally, you could select at what frequency the refresh is done : every page, 1/3, 1.5, etc. But don't be afraid of the ghosting effect, with the time it will not be a problem for you. The advantages of E-ink are more important and with some texts, you'll forget it.
In your case it's only more evident, because you pass from a display (menu) to an other very different.

That's slower and there's more flashing going on (to wipe out the ghosting), so it's usually not enabled by default.
