The additional libraries folder can be organized in a way that allows sharing cross platform libraries between B4A, B4J and B4i. From now on, the recommended way to organize the additional libraries folder: Additional libraries folder is set under Tools - Configure Paths. As you can...
1. The additional libraries path shouldn't point to the internal folder. You can make it empty if you don't need it.
2. Based on the warnings you added libraries to the files tab. Remove them.
