I'm looking at older photos but the sliders are from Lightroom 4 and not my current Lightroom 5 sliders. How do I get the photos to work on Lightroom 5 editing?

I was looking at some old photos from 2012 but when I clicked the files (.dng) instead of opening with the sliders for LR5, it opened sliders for I believe LR4.  How do I get those older photos to open under LR5 sliders and not older versions of LR?
