Contract sends only half of the Resources bag than states in the Contract

Issue description

I have accepted a contract and am loading the ship.
The Ship has 4 sections. The Cargo Depot (4) has 2 Loos Modules M and 2 Unit Modules M
2 In and 2 out
I need 146 Vehicle Parts II ans should get 720 Iron.
I load the ship with round about 190 Vehicle Parts II (Differs every time).
One I get over 146 onto the ship it gets the materials.
When It comes back it has only half of the Iron (360 Iron and not 720 Iron) as shown in the contract.
It also brings back part of the Vehicle Parts II.

Before getting Materials:

After Getting Materials:

Contract:

To make sure that I get more Iron out of the contract then used I build a circle production so that I will never run out of Iron for the Production of Vehicle Parts II but the Iron gets less and less.
Why am I getting only half iron as in the contract stated.

I have tried your save file and the ship brings 720 iron, tried two more times, and it again brought 120 iron. So I can't really reproduce this.

Hi. Sorry that you could not reproduce it.
I tested it again and I could recreate it.
I added a video that shows the problem.

Because of the limited size of the video I had to cut it quite a bit.
The Bug appears not always at the beginning.
Sometimes it needs some Time.
Today it was on the First time loading the Game, the 4th Ship.
After loading it again, it was the First Ship.
I modified the my game slightly so that the needed resources are being produced faster.
If you still can not reproduce it I will test in on an other PC.
Perhaps my Settings or PC is the Problem.

2.save

I tried it on another device with the same result.
This time it was the first ship with this bug.
