Hello Pat,
I am actually using the Mentor Virtual Server to do some tutorials as per on-demand video training. I checked the connectors with error message, it has the correct part number and default terminal assigned (via using cavity component management as well). Please be aware that I used the connector that in the library you provided. By looking into the terminal detail, I can see that the strip length is 5 which seems OK for me. For the splice with the error message, I checked the part number detail, it also indicates the 5 strip length as well.
Thanks
Regards
Andrew
