Ground truth predictions cannot achieve 100% on some metrics?

Hi,

Thanks for releasing the code! I have run it on prediction files and the results look correct. Just one minor issue that I'm curious about: I tried running the evaluation script on the ground truth validation proofs using python eval/run_scorer.py --task "task_2" --split dev --prediction_file gts_val.tsv --output_dir ./ --bleurt_checkpoint bleurt-large-512, where gts_val.tsv contains ground truth validation proofs:

I haven't looked into the code in details yet, but I guess the issue may be related to the alignment process or the process for calculating BLEURT similarity—either some trees don't perfectly align with themselves, or some sentences have <0.28 BLEURT similarity with itself. If you happen to have any thoughts, I would be the most interested to hear. Thank you!
