I am taking it as read that you checked the voltages in EVERY cell were the same if with very minor variation? Now have you used a multimeter to check voltage or even just continuity across each end of the cells in the affected banks. If you have cells that have no continuity across the HOLDER end terminals check that cell for voltage and continuity. Any pair of holder terminals that lacks continuity yet the battery reads OK means that that cell is not making contact with the holder or you have broken traces. Inspect the holder terminals for broken traces. The trace acts a fuse against incorrect assembly. You can repair them with solder. I suspect you do have broken traces in Bank 9 so repair those first. Check ALL the cells again for charge level and charge them individually to the same level. Ensure all the battery terminals are not damaged in any way then reassemble. Let me know how you get on.
Here is the links referring to broken traces.
