KLWP does not refresh on screen but in KLWP App


I am struggling with KLWP (which is by the way amazing - thanks so much!) because it does not refresh on the home screen.

I deactivated battery optimization and even rebooted the device.
The app gets data from a JSON file from a server (which works fine). It shows the current (refreshed) data in the KLWP app but it does not update on the home screen. Even when I set a different background and afterward change it back to my KLWP, it shows the old data.

I attach a screen recording, please pay attention to the first column which should grow in size but does not change at all on the home screen: https://streamable.com/wytuc

Thanks a lot!

Best regards
