Hi,
you can add an empty TXT file to your original package to force the re-publishing since you need the zip file to be "different" from the current, to trigger an update of the files.
You need to use the same identifiers to let the tracking data stay there: if you want to have the current published zip, log as an "administrator" of the course and download it by clicking over the file.
If you want more detail about updating a SCORM activity and the luck of its tracking data:

If you want to get in touch with the files, the next time try to use a File System Repository to host your packages: Selecting an imsmanifest.xml from an unzipped SCORM in a file system repository, https://danmarsden.com/blog/2013/09/24/managing-scorm-content-in-moodle-2-6/.
