Mini converter SDI to Analog

Hi!
I'm using a Mini Converter SDI to Analog with both SDI inputs, MAIN and ALT.
After we shutdown the ATEM mixer wich is connected to the MAIN input, the converter will then nicely swich signal source to the digital signage server wich is connected to the ALT input.
Problem is when we start the ATEM next time and the mini converter will receive signal to the MAIN input again. It would be logical then to choose the MAIN as signal source, but the converter will still be stuck with ALT signal. Only reboot will help with this.
Yes, I have the newest firmware...
