IAR kits show no compiler/debugger warning

QtCreator 12.0.0-beta1

Windows 10

IAR compiler cannot be found from the drop-down list in Kits view which causes IAR kits to always show yellow triangle with an exclamation mark.

Edit:

After clicking "re-detect" from "Compilers" tab, IAR compiler showed up and I could select it from the drop-down list in Kits.
