I have responded to Uli in a private email but I thought I should address this here for anyone watching...
There is no issue with the upload of Uli's parameters. There is confusion between what is entered into ServoCAT-Sky and what is shown in the SCU response.
The SCU response is displaying the parameter values as they are stored in the ServoCAT. The SCU response also has a paragraph explaining that you can save the parameters to a .DAT file on your computer. If you then load this .DAT file using ServoCAT-Sky you will see the entries as you entered them.
I hope this helps anyone else who may be confused by this situation.
