Version 0.1.4: 0% battery means Unavailable ?

[ItsMe00007]

Hi,
i have an AC500+2xB300S.

During the night it discharged battery 1 to 0% and battery 2 to 1%.
In the App both batteries were online, but the hassio-bluetti-bt 0.1.4 Version reported the battery 1 voltage correctly but instead of 0% battery it always reported "unavailable" until the battery reached 1%.

Could it be that the 0.1.4 version interprets the 0% as unavailable ? As mentioned above, the battery voltage was displayed, so the battery info should have been available.

Here's the screenshot from the battery 1 history:
