Trainz

I thought I was starting to understand about editing the configuration file but have met a roadblock.
The LARS tankcars I have placed on my layout all list the same error. "The Product Kuid Is Not Of The Correct Type".
The product kuid in the file is for Liquid Load. What can I change this to, so it shows as a 'Clean' file ?
