Xone23C crossfader fades out too early midway

I recently purchased a 23C and updated firmware and drivers. I had a DB2 before which had multiple fader modes. This mixer seems to be cutting out the exiting channel on the cross fader too quickly. There is a sudden volume drop just past midway. It should be smooth until almost 3/4 of the way.

Is this fixable with an update ?

Analogue mixer? Update?
Did you try the curve switch?
