java – Eclipse– when I try to open a project it opens a library within the project

I have a project at MyProj/ but when I choose this directory at Eclipse IDE Launcher and select Launch, I see in the Package Explorer that it put me inside MyProj/lib/user/MyLib/. I tried deleting the lib and relaunching Eclipse but now it does the same thing but everything in the Package Explorer is unselectable.

How do I simply open MyProj?

Here’s what I’m seeing, all these items are part of the “Processing” library that my java app has as a dependency.

And you can see here the dependency in my filesystem
