How change date format in the INSPECTOR?

Is this a bug? I can change the date format in the main window, by changing it in Mac System Preferences. (See eg. How to set date format in Devonthink).

But the date format in the inspector stubbornly remains as:
M/DD/YYYY
for example today is 5/21/2020 12:50:48 PM

Is there any way to change it to 2020/05/21 ?

No. IIRC that follows your system locale settings.
