New Bighorn 3870FB Kitchen Slide Question

We just purchased a new 2021 3870FB in April 2021 and was curious about the kitchen slide. With the slide all the way out and we try to access the left pantry door it will not open all the way (not even half way) as it hits the corner trim on the top of the slide above the fridge. When I picked the camper up from the dealership and we did the walk through I asked about this and was told that it was normal. When I wrap my hand around the side of the slide I would expect the slide to be pushed all the way up against the wall but it's not, I can actually feel the rubber seal. If I do the same to the back side of the slide (the back being the side of the slide in the living room) it's against the wall as you would expect. I measured the distance on the outside of the camper to see if the distance from the outside wall to the outside edge of the slide was the same on each end of the slide. The front side of the slide, where the issue seems to be (fridge side) slides out 1/2' less than the rear of the slide. Anyone else out there have this model and can share if you are experiencing the same thing.

UPDATE 2/7/2022- I did take it back to the dealership for some warranty work and asked them to look at it. They did adjust it some but the left pantry door sitll will not open all the way, it is better though. Is this just a design flow... hoping that someone with the same model can help shed some light on this for me. The parts for the warranty work are in and I'm taking back to the dealership in a week and half. Dealership is over 3 hours away so just hooking up and asking them to look is not a feasible thing to do. Thanks so much for listening.
