I've also uploaded my notebook of reproduction.https://drive.google.com/file/d/1L-8EHmPC3HIj5Swd_aArrcCjTGZ99Wc6/view?usp=share_link
The only modification is on some evaluation detail, if len(preds_micro) == 0: preds_micro.append([0, 0, 0, 0, 0, -1])#, 0]) # -1 to bypass the count of additional fp
Because the evaluation function requires each pred item of length 6 and GT item of length 7, so I remove the last element in each item. The original notebook has length 7 and 8 respectively though.

After a closer inspection, I think the main reason for the bad result is the low F1-score of micro-expression detection, (I still don't understand why I can't reproduce the results though.) I've found many of my results producing few TPs and large FPs for micro-expression, and thus dragging the result of macro-expression. And there are so many hyper-parameters for spotting to tune, which I believe is crucial to the final result. Is there any search strategy or just tuning by viewing the score plot?

Thanks for your investigation, especially the typo in the original codes.
Please refer to the Jupyter Notebook as I might wrongly copy some parts when converting to py files.
For the modification that you did:
preds_micro.append([0, 0, 0, 0, 0, -1])#, 0]) # -1 to bypass the count of additional fp
You should use the line in the original code:
preds_micro.append([0, 0, 0, 0, 0, -1, 0]) # -1 to bypass the count of additional fp
Otherwise, you will encounter an issue of adding an FP if no prediction is made on the particular video.
See that the FP:7
for the evaluation of CASME_sq Subject 1. In fact, it should be FP:0
.

The hyperparameters were set by using a loop, which will take some time. I think this is normal to do so in the spotting task, and other methods also used a lot of hyperparameters while processing the "signal" graph.

I see. Thank you again for your patience.
