Try charging without connecting the balancer wires, the charger will probably let you know with a reminder or something. Many (most?) balance chargers have a warning and/or require another button push to charge without the balancer connected. If connected it's typically fairly automatic other than setting or confirming the number of series cells correctly.

Well technically the balance only mode equalizes the cell voltages. But for the most part this wastes time for no real benefit. The most common reason cells get out of balance when discharged is they have different capacities and thus end up at different voltages as the same amount is discharged from each. But if such a pack is balanced, then the cells take a different amount to get back to full, which requires more balancing while charging, which takes more time. Simply a waste of time.
