Steam Unrealistic Coupling And Fatal Coupling Bug

One thing which always makes me wonder is, why in Train Sim World still both sides of the Brake hoses are coupled.
In reality, only one hose of the 5bar pipe (HL) and one hose of the 10bar pipe (HBL) is coupled. In TSW both sides are connected and this is very unrealistic and even forbidden in real life. Even wronger is the fact, that both electrical lines (ZS 1000V) are connected between the Locomotive and the first coach. I would really appreciate an update what fixes this.

An other problem I stumbled into is the coupling between the NRM IC Bpmmz (from Hauptstrecke Rhein Ruhr) and the Bmmz (from Frankfurt-Fula) like shown on the first Picture.
If the Bpmmz (white Intercity) is in front and the Bmmz (green Flixtrain) is behind, one of the 5 bar hoses doesn´t couple.

Picture 2 shows the "normal" but still wrong coupling of TSW with all four hoses connected and Picture 3 shows the bug, where the connection of the HL (5 bar) does not connect on one side.
On the last Picture you can see the bug in Detail. Somehow the coupling-head bugs out under the carriage.
The outcome of this bug is, that you can´t release the brake on all wagons behind this faulty coupling.
If you try to release the brake on the decoupled wagon with the "Lösezug" or try to turn off the brake nothing happens. The Lösezug only functions when the wagon is coupled. This is also unrealistic. This installation is a direct connection to the Control Valve of the Brake and should always work like the turn-off Lever.

The other way around is without any problems (Flixtrain first and then the Intercity)

I would really hope for a fix to this problem.
Best Regards

 

SAME thing happens when trying to couple two 378s together.
