There might be a legit reason for the Inquisition there. In my Spanish game, I see lots of inquisitors roaming around inside eastern France (they hold Paris, Rheims, Metz, Dijon, Bern and Marseilles in this game). They aren't bothering me, so I wasn't paying that close attention, but I dropped a spy in Paris, and they are at 27% heresy! Their other provinces are similarly high, all in the 20s. I don't know if it's random, or if it's just the way the AI works, but the AI European powers aren't doing a good job of containing heresy, much less stamping it out.
