I do not know how it turns out, but for some reason the counter with the name "74HC393" sometimes gets buggy, a high level appears on one of its outputs, after which the counter counts to it, for example, a high level appeared on the 3rd output, then the counter will become two-bit, unfortunately I did not find out exactly after what it happens, but after restarting the program, everything starts to work fine, I attached a file where you can find this bug, you may get a bug if you will attach and disconnect the contacts of the chip that i placed below 74HC393, So, it's possible that I'm being stupid, but I kind of checked everything, if this is my mistake, I'm sorry that I wasted my time(( also i I added a screenshot where you can see that I press the reset button and at the same time the signal on the 3rd pin is still high
