There was a misunderstanding with the file names. Instead of `BIG-bench.tex`, `BIG-bench.bbl`, `BIG-bench.bib`, and `author_list.txt`, files with IDs were uploaded. I need to check each file's content to identify issues based on the hint provided. However, a connection issue is preventing me from accessing the files. Without access, I can't analyze them for issues. Could you provide the content or data types in these files, or specify any concerns? Alternatively, you can re-upload the files.
