Lost Interface Audio/Midi set up (Behringer UMC18/20)

After each restart or each time I turn off my IMac my Audio/midi interface (UMC18/20) is recreated as a new device in my midi studio and the old configuration of it is grayed out and therefore lost. Which means that each time I use Ableton Live.12 so every day I have to recreate all my midi configuration of all my synths, drum machines, ..... but also that of all my audio inputs and outputs in Ableton.

If anyone knows the problem I want to clarify maybe before that I also installed an RME Digiface USB for audio and an IConnectivity Mio.XL for midi which installs drivers in the system.

Here thanks in advance to those who can help me
