This is nothing that you need to be concerned about. Some components are 
included in more than one library and so exist in more than one place 
when TRNSYS's kernel is looking to find the components that it needs for 
a simulation. This message is just alerting you that more than one copy 
was found and telling you which one of the two (or more) that it loaded.

kind regards,
