Primary oil overfilling

Primary oil overfilling
While doing a service on my bike some months back, I pulled off the clutch cover and about a third of a quart of oil came out. I made a mental note to keep an eye on it.
I've checked the primary oil level a few times since and everything seemed okay, but after the latest engine oil and filter change, I noticed it was shifting hard like it had when it was overfilled. I pulled the cover and yep, it was overfilled. Somehow, from somewhere, oil is getting into my primary.
A little background: I use the service manual for the 5k and 10k services and fluid levels. The only deviation is that I change the engine oil at 3k miles. The bike is a 2009 FLHTCU with 30630 miles on the odometer.
I suspect a seal is failing behind the stator?
Any suggestions would be welcomed!

I haven't noticed the engine oil going down, but 6 ounces less in the engine is a lot less noticeable than 6 more in the primary.
Primary oil gets changed when the service calls for it, I do check it with the bike upright on a lift, and I'm adding the called-for 38 fluid ounces of oil, bringing it to the bottom portion of the clutch assembly as indicated by the manual.

I'm confident it's not coming from the transmission, and I know I'm not overfilling it, so that only leaves one thing... it's gotta be coming from the engine.
The question is how.
I should also add that the primary gets ridiculously hot, and I don't remember that happening on my Softail.
I need to figure out how to explain this to the shop. I would rather have it fixed under warranty now instead of waiting around for it to completely fail after the warranty has expired.

Seems like it would be a good idea to remove the derby cover before draining the primary fluid. This way a leak might be discovered early on.
