Slider of Servo doesn´t move in Softwarejacdac

[MKleinSB]

Describe the bug
The slider of servos does not move when using Softwarejacdac
The motor itself moves, but not the slider.
The error does not appear when using the kittenbot Jacdacset 2. This works because it´s hardwarejacdac.

To Reproduce

Slider stays at 90 degrees
