OSTC4 battery volt instead %

[Caper]

Hi everyone! After updating my OSTC4, the battery charge is now displayed as volts instead of percentage! How can I fix this?

Everything's OK! I updated the firmware again. As described below, I fully charged the battery and the percentage and voltage readings appeared. They're a bit off, but nothing critical. Thanks everyone, and happy diving. Regards.
