modal analysis post processing

Hello

I did a modal analysis of a MBD system. I made a contour plot of displacement in HyperView to watch the different modes. In different modes different components of my system are hidden automatically. 

Mode 1: the whole model is shown

Mode 2: the upper part of the model isn't shown. Although it should be applied.

I dont know if there is a mistake in my model or if it's a problem of the way of presentation in Hyperview. If it is possible that the problem is caused by HyperView, I hope someone knows the right way to do this.

Thank you!
