ListSource Help, Two Owners

[Brandon Morrow]

We are just starting into our wholesaling real-estate business and just bought our first two lists form LIstSource.  When I exported my lists it returned two different owners, Owner 1 Label Name and Owner 2 Label Name. When I put these lists into my skiptracing software, which list of names do I include? The owner 1 list is complete but there are quite a few entries in the owner 2 column. What exactly is the owner 2 column and do I need to replace the owner 1 with owner 2 for skip tracing? Thanks for the help!
