Plotting Issues

I am working with Draftsight 2017. I was working with Draftsight 2015 prior. I have been plotting items I have created with DS2017 with no problems, But when I go to plot something I created with DS2015 it is going outside my sheet lines when plotting. I am not sure what is going on. I need to get this straighten out as I have many drawings done in DS2015. My plotter has been plotting wonderful when I plot drawings I created in DS2017. My templates all work great when plotting. They are working better now in the DS2017. When I was doing my plotting in DS2015 I had to specify then grab my sheet as a window then plot. I am not sure how DS2015 was setup as I was not the one who had it first. I have been moving things as needed when I have thee issues then my drawing looks unprofessional. Any help with this would be great. Thanks for any help and input.
