Bug in ClientConfig?

Hi,

In CC i made a setting [[++Mysetting]] , set it to checkbox and gave it a value ‘MyValue’.
Now save the configuration and go to client view check my new setting. Now the value ‘MyValue’ appears on the page… Great. Now i unchecked the chekbox and the value ‘MyValue’ is not on the page anymore Still… great.
But when i now check the checkbox again there is the value ‘1’ on the page instead of ‘MyValue’ ???

I’m using CC 2.1
