I have updated from 3.86 to iCUE v4.13.223. Uninstalled 3.86 first and installed 4.13. Everything works fine except for device settings on my RM850i. It defaults to singe Rail mode. I try to change it back to Multi Rail but it doesn't seem to take effect. When i try to go back and change it, it just shows back as single rail mode. Am I missing some step to do?
