Hi @nick,
If odrive sees that a file exists it will perform a “update” which will update the file rather than uploading a new file. The tricky thing with Google Drive is that it will freely allow you to have files with the same name in the same folder. So, if for some reason, odrive doesn’t see that the filename already exists, it will upload it as a “new” file rather than a “new version” of a file. Google will accept it, and now you have 2 files with the same name. This should not be happening, generally, though. It would take a special set of circumstances to create this type of scenario.
In general, odrive will only show the most recent file, if there are files with the same names. If you choose to delete a file, that file object should be deleted, but then you may see the next most recent file with that name. If you delete that, I would expect it to be deleted, revealing the next in line, if one exists.
Now that all of that explanation is out of the way, can you tell me if your particular scenario fits into the above? If not, are you able to reproduce the issue and then send a diagnostic from the odrive menu? I can take a close look. Please give me the path and filename of the file, also.
