Hi Terry_1100,
Thanks for the follow up. We're happy to assist with additional steps.
If you've followed through all of those steps and are still having the issue, your backup may have brought the problem back. Next you'll want to set the device up as new to test if that resolves it.
Again you're going to begin by backing up your device: How to back up your iPhone, iPad, and iPod touch
Then restore it: Restore your iPhone, iPad, or iPod to factory settings
This time after you restore the software on it, go through the setup menu and choose the option to set it up as a new device. Do not restore your backup like last time. When you finish getting through the setup menu and are back to the home screen check Settings > General > iPhone Storage, to see if it shows any other categories in the bar or if it still only shows the App category.
If it is showing all of the categories in the bar when set up as new, that will indicate the problem is from your backup, and that would be why the previous steps didn't appear to resolve it.
Take care!
