Is It Normal for Roof Rack on 2020 Ford Escape to Not Be Level  

I have a 2020 Ford Escape with a naked roof. I recently installed a Yakima roof rack using the Baseline tower system, 60inch crossbars, clips 137 and 152. I installed everything to correct measurements and pitch angles per the Yakima instructions the crossbars are supposed to sit 28inch apart measured bar-front to bar-front. At that distance 28 my rear crossbar sits higher than my front crossbar, because of the roofs curve. If I put the rear crossbar at 31.5inch distance, it sits level with the front i.e., same height off the ground I checked with my construction level, and I can still attach the clips securely. The rear crossbars pitch angle seems fine at both 28inch and 31.5 Is the rear crossbar supposed to sit higher than the front crossbar? Or is it supposed to be level with the front crossbar ?
