14% capacity left is exactly what the charger is estimating. Every battery meter uses a little different voltage reference to determine capacity, so it's just an estimate. But each cell should be down probably around 3.4v.
If that's the case, the charger when using storage mode charges the battery to storage voltage, instead of discharge. Pretty sure this charger, like most of them that use this software use 3.8v/cell as the storage voltage. Storage mode uses either a discharge or charge depending on what it needs to do to bring the cell to the storage voltage.
