How do I have a different menu appear if you are apart of a certain membership subscription?

I work for a manufacture who distributes commercial and residential robotic pool cleaners. I have installed the membership plugin and I am hoping to create more in depth menus for users who are under the employee subscription. (I am starting with the group employee first hoping I can find the answer and then further develop the same thing for someone who might be a dealer)

I have gone into the membership dashboard and clicked employee which then gave me positive and negative instances. I clicked to select the menu i created specifically for an employee under positive but then no menu was listed.

Can anyone help me out with this? I have specific content for employees that is meant for internal uses only. I am really hoping I can concur this so it will benefit the company!
