Default Compressibility in incompressible flow mode

Streamlet is on a distinguished road
Dear All,
I am simulating a GMO problem, using incompressible flow mode and implicit with automatic limited compressibility pressure solver option. However, in fluids properties, the compressibility for fluid1 can be changed as you want. I am confusing. Why we can change the compressibility in impressibe flow mode? On the other hand, I also found that different compressibility numbers influence the flow field significantly. Can anyone help me? Thank you in advance!
Yours Streamlet
