Windows 10: Show time and date in the System tray is greyed out

Hello!"Show time and date in the System tray" is greyed out after latest updates, Time clock in tray is just dissapeared firstly, and after I looked at this option in "Settings" and I'm not able to do anything with that.Default options like: sfc /scannow, dism.exe not helped. Nothing done in "regedit" before update also.Updated to latest from "Windows Update", from "Microsoft Store" all updates also downloaded. No apps installed to change any settings with windows 11 or similar to that kind, beside "BloatyNosyApp".What can I do?

Different date formats for File Explorer and System Tray

Hello,

I recently updated the system tray's date format by adjusting the short date. But now I noticed that when I open
File Explorer, the date format for Date Modified and Date Created is the same as the one I created for the System tray. I don't want it to be the same date format as I'm using in the System Tray. I would like for File Explorer to use a different
date format for Date Modified and Date Created properties. My questions are:

1. Is there a way to have different date formats for the System Tray and File Explorer?
2. On the system tray I show the day of the week (long and not just the first 3 letters). Always on Wednesdays, the date will not show and the system tray will only show the time. Why is this? How can I fix this?

Thanks for your help,
