What version of firmware are you on?
I notice, at least now ( I have no idea when these new fields were added ), there are two more required fields in the LogTriggers. One is "CommandsGlobalMode", which is a simple toggle on or off. The other is "AccessProfile". Both can be null, but the elements must exist. So, try adding these two elements to each of the log triggers:
<CommandsGlobalMode>on</CommandsGlobalMode>
<AccessProfile/>
