Having a problem with the multiple computer setup for ISBoxer

Following the setup guidelines I have the main computer character set, Main, set to also launch the
character sets for the other two computers, Box1 and Box 2.

My problem is that it is only launching one of the other character sets, never both.

I can change it to only launch either one, after exporting the config to all computers and it will launch that one, but I cannot get it to launch both.

Manually launching that character set on the other computer doesn't work as it will not pass the mapped keys or repeaters.

Anything I should be looking at as far as the config or anything in the logs?
