That's a different scenario and shouldn't result in out of balance cells. Individual voltages should be identical as they are in Parallel. It could in fact be a BMS issue or your SOC meter being out of calibration.

Most SOC meters will reset to 100% after a full charge and this is required to give the Coulomb based SOC meters (a must for LiFePO4) a starting point as they will drift over time. Have you completed a full charge recently? Also, when left for prolonged periods, SOC meters will loose count as they will not pick up inherit charge loss or power consumed by the BMS. A full charge will solve both of these problems.

Cheers
