How to restore LR color presets

I created a specialized preset for use when opening files from my Fuji X-M1 that had been modified with an infrared sensor. The problem now is that when I go into any files, however old, and from whatever camera, Lightroom applies the IR preset to every image, in every folder.
How do I get Lightroom to open files using the original color preset and ignore the IR preset?

I have attached two photos. One is the Library module showing the excessive blue tint because the X-M1 preset is being applied to all the photos in the folder. But some are not, which I don't understand. The other photo is a closeup of the Presets panel. When I open up older photo that I want to work on, I just want LR to use the default presets it would have used in the past. How do I get LR to forget about the X-M1 preset and use only the original Canon and other Fuji presets?
