Circular variable dependency detected

I am finding this error message while solving an evaporation problem.
In my Heat Transfer in Fluid Model, I have added a energy source which is dependent on the saturation pressure and the partial vapor pressure.
My boundary heat source equation is A*B*(ht.psat-ht.xvap*ht.pA)*Lf [W/m^2]
where ht.psat is the saturation pressure
ht.xvap is the vapor mole fraction
and ht.pA is the absolute pressure. All these three variables are in-built comsol variables.
And Lf is the latent heat of evaporation
I have added Transport of Concentrated species to solve the species equation where I put a mass flux that also comes from the expression A*B*(ht.psat-ht.xvap*ht.pA) [kg/s.m^2]
When I try to run the smulation it shows me "Circular variable dependency detected.
- Variable: comp1.ht.omega_moist"
Any idea how to deal with this?
