WiFi router:  Archer AXE75(EU) v1.0 AXE5400 Tri-Band Wi-Fi 6E Router

Hi,

I've updated the above mentioned router to the latest firmware version. See the header of the system log:

The update file (axe75v1-axe5400-up-ver1-1-9-P1[20231115-rel37295]_nosign_2023-11-15_15.46.25.bin) was first downloaded on the local HDD and then installed via the router's dashboard (Advanced > System > Firmware Update > Local Update).  All went well as can be seen from the System Log header.

However, upon login into the router's dashboard there is the message to update the latest firmware version to the same latest version of the firmware?!; see image below.  So, what could be the reason for this?  And how to solve it?

Thanks in advance.
