Blocks not recognized when linearizing in Simulink

i have created a model for a coupled vibratory system and wish to use linear analysis to identify the amount of damping in the system. When i linearize the model, some blocks are not linearized as shown in the image above (not highlighted). i have already specified values for the variables and i would assume they are constants. it would be very helpful if someone could explain to me why is this happening. thank you.

The blocks that are not highlighted are not on linearization path. All it means is that graphically the input linearization point is not connected to output linearization point through those blocks. It does not mean linearization results are incorrect - the impact of those blocks is still captured by linearization algorithm when it linearizes the product blocks.
