Charge voltage is set too high. If you can't adjust the voltage on the charger you can draw down the pack some and then plug it back in and watch it charge on your app. When you are drawing on the system they should be in pretty close balance, same as when you start charging again. Then you'll watch the individual cells and see where 3&4 start to rise up way past 1&2. Then at the pack at the point you'll set your BMS to stop allowing charge in. That's only if you can't adjust voltage on that little charger.
In all your photos your BMS cut charging, it's good that it did because that shows it's working but the BMSs intention is to be a monitor and not play a role in every cycle but only get involved if need be. I'm also looking back to see if you out up a photo that shows good pack balance at rest or load. Need to confirm they're balanced before anything else.
So I say
1. Charge voltage too high.
2. Do the test above where you watch the cells rise. When a cell or two start diverging, note the total pack voltage and set the charger to stop charging then.
3. List your components next time so we have a better idea of what you're working with and what limitations there are If any.

Double check battery capacity.The battery is protected with a Daly smart BMS 60A that I still hope is appropriate for a 60Ah battery
