as mentioned previously if packsare new speak to supplier to see if they have had any more issues with these packs
If your program box is accurate and i dont see why its shouldnt be .Then if a cell had failed i would expect the "duff" cell to be well below 3.0 volts or dead at 0 volts
it certainly looks "out of balance by a fair way but not un recoverable
if your charger charges all your other batteries fine then i dont see any reason to point finger at the charger or replace it
poor Connections can make a big difference as recommended check or replace charge leads
failing that ask a freind to try to balance charge it for you which eliminates all your kit totally
