What is my trim level?!

I bought a 2019 Ram "Rebel" almost a year ago. Love the truck but have been confused.

So the VIN lists this truck as a Rebel, but the screen inside on startup says "Sport", the tailgate says sport, but any site you try to look up parts and stuff doesn't list a sport trim.

Looking up what a rebel actually is, my truck is not a rebel. Doesn't have that funky interior, has a the beefy axle for towing, blah blah blah..... Anyone able to explain this to me? I'm more looking at what trim should i select on these sites to get the right stuff?
