Tr004 firmware update fails!

Hi,
Conneted the TR004 to a Windows-11 PC. Installed Firmware showed 1.2. Ran the update process on the PC but no change. Seems that the current firmware still is running on the TR.
After re-connecting the TR004 to my TS431 it shows that a new firmware 1.2 is available. No Version is shown for the installed Firmware. Weird

I‘ll ignore the update message until a new firmware version will be mentioned in the update section.
