are you sure you want to delete the selected song from your itunes library

Every time I delete a song I get a box asking "are you sure you want to delete the selected song from your itunes library" and a little check box saying "don't ask again." I check the box but it asks again every time. I reset all warnings in prefs-advanced and it did nothing. Any way around this? Itunes 12.2.0.0145

Thanks
