Modes not Showing on Modal Analysis

  I have two different films I am comparing; they are both of the same dimensions. One has a psuedo-random grating design, and the other is a closed solid.
  
  I have specified ANSYS to show 6 modes upon solving the Modal Analysis. I am not sure why only 2 modes are showing for the film with a grating design, but all 6 are showing for the standard one. The first two modes appear to be the same.

  Hi,
  
  In the Analysis setting check for number of modes to extract and number of modes to expand.
  
  Make sure it is 6 for 2nd analysis too.
