Phantom Pantone swatch in Illustrator document?
I am trying to work with an InDesign document, and I am getting a weird phantom Pantone color whenever I place an .ai or .eps file. In the Illustrator document itself, there is no orange swatch.

When I place the document into InDesign, the image remains green, but adds an orange Pantone swatch to my swatches (I guess it's linked to the .eps file somehow?)

What's frustrating is that when the file is exported (interactive PDF,) the green outlines all show up as orange.

How do I resolve this? These files are not originally mine, so I'm not sure where to look to troubleshoot. I've combed through the layers to see if there's anything hiding in the .eps file, and I've tried deleting the object and recreating a new one from scratch. I don't know if this issue lies in the InDesign or Illustrator document. If I copy and paste anything with a green outline from Illustrator to InDesign, it shows up with an orange outline.
