PlayStation Db Br 146 Lzb Discplay Not Working

Picture taken from Aachen bound RE1 service on SKA.
As you can see from the picture above, the LZB in not showing up on the in cab discplays. However the LZB is still working as it still adjusts the AFB according to speed restrictions. It just doesn't show up in the cab. This picture is taken on the new 146 that came with the Nahverkehr Dresden, with all the safety systems and AFB on. However this bug is affecting the MSB version too. This is really immersion breaking and it would be great to have this fixed.
