Project Plugin C++ classes not showing in content browser

I am taking a plugin and making some modifications to a few pieces of code, but before i can even do that i am having some issues. When placing the plugin within my project folder, i do not have access to the c++ classes that are in the project. When adding the plugin through the typical marketplace/engine, the classes appear. They appear in the VS solution, and the code compiles in VS without issue. I have the c++ and plugin content enabled in my content browser. I have tried cleaning the directory, regenerating the sln, and i am able to see other c++ classes in the content browser, just not for this plugin. Any ideas? I am hoping im just missing something dumb…

Classes in the .sln:

What i am able to see in the content browser:
