This is not the first time I have extracted zipper files with 7z, with rather long paths, and I end up with files with the same name that fails to extract correctly and then when I go to the folders some of the extracted files have added a space at the beginning of the name, which is not present in the original file. On top of that, some other files are listed by the dir command as having the beginning space, but shown without space by file explorer. On the other hand, it is also not possible to rename these files, one of the errors I get reads "The names of the source and destination files coincide."
