Incorrect voltage displayed - Blue Smart Charger IP22 24V 16A

Interesting fault...

Output voltage is measuring correctly (with a multimeter) and charges with appropriate current, however the app indicates it's charging at around 18V and 16A (which I know to be false). Latest firmware and app. I've tried cycling power, reinstalling app, reducing output current to 8A, Power supply mode at both amp settings, all of the modes - nothing changes the displayed output voltage from around 18V. Any solutions?

@Sean

If it is that far off and there is nothing wrong with the multi meter, then I would honestly take it back.

what alexandra writes maybe correct

But You dont tell us what the voltage is that your volt meter is displaying ( is it higher or lower than whats indicated) you do say its wrong but by how much - if it is charging at 16 amps then the batteries maybe overly flat
