Modal analysis of a membrane

I am interested in finding mode shapes for a membrane and also its frequency response.
I went about two ways, first i just just the solid mechanics module to check out the mode shapes for a frequency domain say 1-5 kHz.
second, i had the same geometry but used acoustic structural interaction module and found out frequency response at a point certain distance away from the membrane.
The anomaly that i saw was the mode shapes in both these analysis were different.In the first one it was symmetric but in the second it wasn't.
Shouldn't the mode shapes be the same?
