It doesn't matter how many libraries You have used. They are all different.
It's the way to dig and find out that is the common part.
i repeat parts of reply #10 below:
Use Windows filemanager and check what files there are in that servo folder.

Check the details, compare the example array with Your arrays........
There are files, in the library folder, that can be opened by any simple text editor like Notepad, and be inspected. Try that!
