LED order incorrect by default on CRS326-24G-2S+

RouterOS General
1

I have two identical CRS326-24G-2S+ and I did reset the configuration to default. On one switch the interface order shows up correctly, on the other the following LEDs are incorrect:

/system/leds> print
Flags: * - DEFAULT
Columns: TYPE, INTERFACE, LEDS
 #   TYPE                INTERFACE     LEDS             
 0 * interface-activity  ether19       ether1-led       
 1 * interface-activity  ether24       ether2-led

I can change the LEDs manually, but I wonder why they are not set correctly by default. The firware is 7.22.2 on both switches.

"/export" of the device?

You have updated both SOFTWARE (RouterOS) and firmware (RouterBOOT)?

/system/leds> export

…is empty.

/system/leds> /system/routerboard/print          
       routerboard: yes           
             model: CRS326-24G-2S+
     serial-number: xxxxxxxxxxxx
     firmware-type: dx3230L       
  factory-firmware: 6.43.16       
  current-firmware: 7.22.2        
  upgrade-firmware: 7.22.2

…shows the correct version. As I said: One switch works fine and the other shows this behaviour.
