When I updated the treebanks (fixing up the commented out sentences), we introduced additional sentences into the treebank, but not the corresponding sentence-level alignments from Amelia Parrish and Farnoosh Shamsian.
I will revisit the script that stitches the trees and alignments together to see if we can improve this.
