[V8i] A Bug in Display Styles?

Question

I wanna know why Bentley designed this display style but the newly modified settings in wireframe cannot apply on this. I've also tried to find out if there any ways to set the "Default Display Style" when the dgn's display style is undefined but nothing was found. 
 Of course, after defining the display style is "Wireframe", modified wireframe settings will work well.

Hi, 
 This is just a guess. "(Wireframe Display)" is not a display style. It really is a display setting (not style) from prior versions of Microstation, before they had display styles. So with the "(Wireframe Display)", it does not have the framework to save what you want. The new version is "Wireframe" and does have the appropriate framework to save everything. So once you set it to "Wireframe" and save settings, you will never see the old-fashioned "(Wireframe Display)" again and you will have full functionality.
