It's my problem
• Create a device that controls LED and buzzer using 3 buttons.
• Buttons are located at the top, middle, and bottom.
• 1 button: When the button is pressed, the 3 red LEDs turn on for 0.3 seconds in sequence and then turn off.
• 2 button: When the button is pressed, the buzzer sounds for 0.3 seconds in 3 steps in sequence.
• 3 button: When the button is pressed, the 3 blue LEDs turn on for 0.3 seconds in sequence and then turn off.
• The above function is repeated until the button is pressed again.
Constraints
All functions are performed with the operation cycle synchronized.

If you press the first button randomly among the buttons once, the red LED lights up in sequence. But even if I press the first button again, the led doesn't turn off.
And when you press the first button, the function of the first button is repeated, right?
After that, when I press the second button, the buzzer should repeat, but it doesn't work. The problem is the same with the third button.
When I saw it, bool seems to be the problem, but I lack the ability to solve it. What should I do?
