For the tutorial "Packed Bed Latent Heat Storage", why the density is constant in the results?

Dear all, In the model “Packed Bed Latent Heat Storage”[https://www.comsol.com/model/packed-bed-latent-heat-storage-76181], the density of water is defined by two temperature-dependent equations, as shown in the picture.
After computation, I try to evaluate the temperature and density of water by expression “ht.porous.fluid.T” and “ht.porous.fluid.rho”. However, the density is a constant value with temperature change.
Does anyone know why the density is constant? Thanks a lot.
