Forgot to add, those "525" errors were when I loaded a larger project, probably representing 1 error per class.

Please provide more information in the form of a scaled down example that contains warnings that you did not expect. Thanks.

Editor build #­4918 is one of those builds when we were in the midst of transitioning from libraries view to files view. Please try it in the latest build and let us know id you still see these issues.

Should be fixed in our latest integration build (5104).
