Problem with neon pink on 5D3 pictures

When I take a picture with my 5D3, no matter which lens I use, the color neon pink looks fine in the RAW file, but when I open it up in ACR it has a solid gray line around whatever is pink. It's in every image, whether it's with a 100mm macro, 100-400, 24-105, etc... Here is an example of what I mean, look at the edge of the pink shirt. It isn't because of how I edited, because it's there as soon as I open the file in ACR. It also isn't because of how bright the shot was, because I was shooting high school football night games with the same result, as the kids wore pink for breast cancer awareness month. Any clue why, or how to prevent this?

Looks like you've got some massive purple Defringe set in your ACR defaults.

Go into Lens Corrections --> Color and check the settings in the Defringe section.

Thanks! I didn't change anything, though, the gray is there from the gate. Reducing the slider fixes the problem, but I need to do it with every image that has pink in it. Also, I use a 6D along side my 5D3, and I never have an issue with those images, even if it's just taken seconds later. It only happens with my 5D3.

Chromatic aberration. If you change from portrait to landscape you'll see it I different amounts too. The gray outline is from auto defringe from lens settings. It varies from lens to lens.

You can setup ACR default settings for each specific camera you own by model or serial number. You can also create default settings for each ISO value.
