Hi @dannis1, thanks for posting here today!
How do you sync your camera uploads to your device? Do you use a cable to connect the two, or through the mobile app?
I'm asking because the setting you're referring to (in the Dropbox Preferences) should apply to any files that sync from the website.
So, for example, if a file is added to a folder online, it should sync locally as "available offline" or "online only" depending what you've chosen.
When you manually change the status of the camera uploads folder or its content, do they remain "available offline"?
Let me know more!
