System command editor - Mobile Problem

So I have used system command editor to create 4 buttons to turn on and off the power and the LED lights using smart plugs and IFTTT. When using this via a laptop, it works fine, but when trying it via the IOS app it does not. When pressing a button I get an error saying Warning Failed to request to execute command. This only happens on the buttons I have added. The one to reboot etc work without issue on the mobile app.

Any ideas what would cause this.

Thanks Laurie
