I see from your list you are using pins 0 and 1, these are used by the serial port, so if there is any serial printing going on in your code this will mess up the reading of these pins. I can’t tell because you posted a .ino file. These can’t be read on mobile devices. While it is not shown as the bottom right it could matter.
What is shown is pin 13. This is connected to the on board LED and it could be that this pin is being left as an output, or input with a unwanted pull up resistor.
A schematic showing the wiring for a few of the hall sensors along with their part number would help to clarify matters.
