That is correct rear main seal & oil filter housing both replaced. The JK is about to hit 90k miles it’s a 2016 automatic
If they didn't screw up the rear main seal install, which is possible, there is a bead of rtv along the back of the oil pan. If that bead was broken when they installed the rear main (and those rubber plugs are access holes for two of those bolts), then it will leak between the block and the top of the upper oil pan.
If you check the video I posted earlier, at about the 10:00 mark, the guy in the video has his rear seal replaced but the rtv seal was broken during replacement, causing it to leak from the upper oil pan.
He explains it in the video. Either you have a rear main seal that was installed incorrectly, or the upper oil pan needs re-sealed to the block with RTV. Or both.
