All files showing up as "Imported Object"

Hi,
All new scripts created using the right-click menu → Create → C# Script are showing up in the Editor as “Imported Object” when this is not the case (see attached for newly created example script)
This is on Unity version 2021.3.11f1 - is anyone able to help?

Thanks
