The photo in the original post doesn't look normal to me at all. My oil catch can has always caught oil. I just emptied mine after a few thousand miles (not really sure, just a guess since I don't empty it that often). I have a 2014 Forte5 Ex with 62,000 miles now. I've had a Tork Motorsports tune since May 2019 (at 49,000 miles). I added my catch can at the same time I had the tune done.
