Config. rejects mates.

Hello;

        Have a situation where I have 3 different configurations, certain mates work for certain configs., two to be specific, but then don't

for the 3rd; it rejects them. I then repair them in the config., but the it rejects them in the other. A possible work around might be to

create separate mates for each, but things are a bit confusing already and these concentric, & coincident mates are the same in

the various configs. Why does it reject them just going to a different config. ?  I've seen this before also.

Thks in advance for any input;
