Crankshaft/camshaft timing don't align yet engine runs fine.

2006 KIA Sorento 3.5L engine. Will be replacing water pump and timing belt, but ran into an issue that won’t let me continue. Car was running perfect prior to starting this job. I’ve done several timing belts and water pumps on various vehicles. I’ve removed the upper and lower timing belt covers and associated components. I lined up the timing marks on the four camshaft sprokets. Don’t want to continue until I clear up the issue I have.

The issue is that when I aligned the timing marks on the four camshaft sprokets, the timing mark on the crankshaft was off by four teeth. Crankshaft would have to rotate 4 teeth clokwise in order to align with its timing mark. Why is this happening? ‘

Looks like crankshaft is set for cylinder 6 at TDC, yet the camshafts are set for cylinder 1 at TDC. Engine was working fine. The belt hasn’t been taken off.
