Document header and footer change

I can open a new document and all is ok, then if i open a new or existing document I have noticed my document 'status bar' has changed to have 2 lines of copy at the top and t 'status bar' at the bottom with document information has vanished.

This change remains if I close all windows down to one and only re appears when I open a new document. I do not use the application frame and all seems fine when using the frame.

I have uninstalled and gone back to InDesign 20.1 incase it was an update issue, the same results, I've also reset my Adobe InDesign preferences.

Any ideas or am I going mad.
