If you click uninstall for each mod, it will display the files that were edited, you can look for Load.php. If you delete a mod, it doesn't uninstall, but you will not be able to uninstall it if you need to at a later date. Don't know why 2.0.15 is listed twice, but if everything's working, wouldn't worry about it. If a package is installed twice, you can end up with duplicate code that can cause problems. You can revert to 2.0.14 using backup in /Packages/backups/, then install .15 patch again.
