Simulink Linear Analysis Not Available

I'm currently running MATLAB R2018a on Mac, and I cannot access the Linear Analysis Tool on Simulink. I have a Simulink model, and I would like to use the Linear Analysis Tool and the Control System Designer. I have been following tutorials on mathworks.com to achieve this, and I noticed that all the tutorials launch the Linear Analysis Tool by selecting it from the Analysis > Control Design tab in Simulink. However, when I attempt to do this, I am only presented with one option: Model Discretizer, as seen in the photo below.

I have looked online about the system requirements, and I learned that I need "Control System Toolbox" installed in MATLAB. However, I do have Control System Toolbox installed, so I am unsure why this is not available to me.

If anyone has any insight on this, it would be greatly appreciated. Thank you.

LInear analysis requires a Simulink Control Design license. Do you have a license for this?

In adding the licencse to the student license I already have, what do i do? Also If I add now to my license due to expire soon, will the new license expire same time or it expires in a year time (long after my current licence expires)?
