Uploading and overwriting folders in GCP Console / Cloud Storage / Buckets / Folders

[MA2014]

Hi Google community, Our process for uploading new content to our bucket files doesn't appear to be working? our process for overwriting buckets/folders that are already live with updates is to: 

1. Go to folder within Bucket on GCP Console

2. Click upload Folder

3. Select file to upload (extracted file, folder name identical)

4. Pop up box asking for actions: select overwrite and then apply to all files and upload

The above steps would usually overwrite the Content folder bringing in new changes to the following folders:

Assets, Goodbye.html, Index, Lib, Locales

However, now instead of this it is bringing over all singular files within the above folders and our URL appears blank.

Advice greatly appreciated.
