How can I get the titles to show on my folders?

I have an iPad Pro (12.9-inch) (3rd generation) which has been updated to IOS26. Unfortunately I have lost the names of my folders which is very annoying. I would be grateful for any advice to get them to show. I have ungrouped a file and regrouped it to see if that would work but it didn’t.

The name of the folder does appear when I select an individual group so I don’t understand why they don’t show as normal. Yesterday I downloaded IOS26.1 hoping there would be a fix but I still have the problem. I’m including screen shots to show the problem.
