Data Source Data Generator step won't work when used via loadtestrunner.bat

I'm using  a Data Source Data Generator step to populate a value in subsequent step but for some reason it's not taken in account when used by loadtestrunner.bat  ( and Performance TestRunner).

At the same time when I use it in the UI everything works correctly.

The DataGen step also works correctly when used in script mode (but I see it's deprecated and the suggestion is to use Data Generator of Data source).

I attach the demo project where the issue is clearly visible (using Fiddler to sniff the API requests as I haven't found a way to debug request from TestRunner).
