PySimpleGUI - can't update text fields

Question

This is my first try with PySimpleGUI.

I've written a simple window with three output fields:

The window paints fine, and the default values display. But I can't get any of the fields to update.

Am I doing something stupid (almost certainly!)?

Here is the code and result: Code Display

Thanks in advance, Chris.

I've tried multiple field types and various options to try to force update, all to no avail.

Something wrong

sg.Window(...).read() not return window, but event, values. It also block the execution until an event happened. It looks the only event is to close the window, then the GUI cannot be updated after window destroyed.
window[key].update(...) return None, None don't have method read to call. Method update won't update the GUI, but the configuration in PySimpleGUI.
Should update the GUI in the event loop where the window.read called after any actions for specific event.
time.sleep(30) will get the GUI no response for 30 seconds.
