OpenKNXproducer "new" doesn't generate a valid knxprod

[somnatic]

Hi
Running the following command
OpenKNXproducer new --ProductName=DuWx2S --AppNumber=890 --AppVersion=1 Test2

produces an invalid knxprod file. When importing, ETS 5.7.7 will state:
File: C:\Users\lith\bin\Test2.knxprod
Cannot convert into ObjectSize
Parameter name: value

I'll test with an earlier version of ETS in the evening.

Different computer, but also ETS 5.7.7 - doesn't work as well. Can anyone try an older version?
