it looks like beaTunes 'hung' on moving a file to the trash. Was there perhaps an open Finder dialog? Does the file /Users/jennytrick/Music/iTunes/iTunes Media/Music/My Favorite Highway/Unknown Album/02 Unaware.mp3 still exist?
I took a screenshot of what happens, as you can see on the left there are duplicate "1000 julys" by third eye blind and duplicate 11PM by nickasaur. I went into preferences and the duplicates option is enabled.

thanks for the screenshot. Indeed beaTunes misses those two duplicates.
In the first case the song lengths differ by 10s. beaTunes has a built-in threshold for different song lengths. I.e. if the lengths are too different, the songs are considered two different songs, not duplicates. 10s is unfortunately just over that threshold (+-4s from the median of all candidates).
In the seconds case the difference is smaller, but the title is spelled differently enough to make beaTunes think this is a different song. The deciding factor here is the extra space before pm.
However, at least the second issue can be worked around, by fetching MusicIP PUIDs for all your songs. To do so go to beaTunes' Tools menu and select Get MusicIP PUIDs.
PUIDs allow beaTunes to determine whether a song is a duplicate or not regardless of its title. Unfortunately, as the PUIDs are created and administered by a third party service, I can't make any promises as to whether this works 100% or even in this particular case. But if you want to find duplicates, first fetching the PUIDs is a really good idea. And since your library isn't all that big, it won't take that long, either.
Generally, it's often a matter of opinion, whether a song is really a duplicate or just a different version of the same song.
