Boeing 747-8 – "FUEL PMP STB R/L" Message despite pumps running and enough fuel in tanks

Hello,
yesterday I had my first longhaul flight on the AAU2 747-8 (HND-FRA, ~14hrs real time). During flight I noticed a small issue the fuel system, In this case, messages for the Stab Tank pumps, that appear incorrectly:

Boeing 747-8 after AAU2

Brief description of the issue:

The messages “FUEL PMP STB R/L” appear on the EICAS, despite there being more than 500kg in the trim tank and the pumps running. If I switch off the pumps, the message disappears. According to the QRH, this message should only appear if both of the following conditions are true:

  1. more than 500kg in the tanks (true)
  2. the stab pumps are switched off (false)
    So the behavior of the message seems reversed with the stab tanks pumps being on or off.
    The messages disappear (correctly), once the fuel in the stab tank is drained below 500kg left, no matter if pumps are on or off.

Detailed steps to reproduce the issue encountered:

Fill the Stab Tank with more than 500kg of fuel and switch on the stab tank pumps, while also having enough fuel in the center wing tank.

Attempting to actually fly the long hauls, I inevitably wind up crashing into the sea, every time, if left unattended. I’m on PC Steam.
