Because you have cropped the screenshot and have not given us any idea what layer the options in the Extended Graphics panel are point to, but they are obviously not pointing to anything in the Comp that is selected (Output_Vintage_Startup_Title) because the only layer is a nested comp called Startup. It is also highly unusual to be editing a comp by selecting a layer in the Projet Panel. That layer could be anywhere according to the Project Panel the Dark Gray Solid is used 3 times in the Project.
You also moved the CTI to the end of the timeline and then the layers dissapeared so I don't know what the out points for the layers are in the nested comp. I don't have any idea how you have setup the MOGRT. We need workflow details, a flow chart or the layer that is driving the template revealed. There could be a bunch of problems in the setup.
You could also share the MORT or the AE project so we could discet it. I strongly suspect user error.

I tested the original MOGRT and AEP and everything worked as expected except the type on type color. I changed the color of the Gray solid using the Layer/Solid Settings menu and selected all layers and everything worked as expected except the Fill color so I dug down into the Tagline comp and found that the Fill effect had been turned off. When I fixed that everything worked as advertised.
I'm not sure why your MOGRT doesn't work but the one that I saved works just fine.
I don't know who designed that project but it is way more complicated than it needs to be.
