there is no way to guess what the problem is without measuring the cell voltages.
you need to use the normal sequence and start with #1 at the bottom or others get confused.
you dimensions are off by about a factor 10 too. 1/4"=6mm. most pouches are 7-8 mm thick too.
you should be able to discharge the battery from the red and black wires coming from the BMS. but measure the cell voltages on the sense wire harness.
you can build a constant current discharger, but it would require extensive electronics experience. frodus sold one recently but it was more than your battery would cost new.
of course the current will change as the voltage changes so you have to make accurate regular measurements unless you have a wattmeter. then you can integrate the current over time to find the amount of charge delivered. you will need a wattmeter or cycle analyst anyway so this would be an opportunity to buy one.
