git reset not affecting gin commit

Want to undo a "gin commit", tried `git reset --soft HEAD^`, which does work as git put the files back into files to add. gin status on the other hand still shows the files as LC.

When doing `git reset --soft HEAD^` and erasing the data, it looked clean. but at the next gin upload, the data was put back in. And gin seem to try to upload it. the commit message was also not used during the upload of the one file (the upload worked).

any cues?
