Mitsubishi plc ladder control

This is the control requirement I saw on the tutorial: I asked to press the start button X1, the red light Y1 lights up for 5 seconds, then the yellow light Y2 lights for 3 seconds, then the green light Y3 lights for 6 seconds, and finally returns to the red light, so Loop control. The ladder diagram is as follows, but the simulation results on the Mitsubishi plc simulation software are not the same as the control requirements in the title. Is the program wrong?


X0 is the manual automatic selection. When automatic is enabled, the X1 conveyor roller is automatically operated. When manual is enabled, the conveyor roller is manually operated after pressing X2. Y0 is the conveying roller operation.
