[Touch Bar] Battery Widget displays remaining time instead of percentage

the Battery widget seems to have bugs related to remaining time.

I've configured it to display only percentage, not remaining time.

After a while, it displays "∞", which is a remaining time information.

If I open BTT, it changes to "??%" instead of percentage, and after messing with is in the prefs for some time, it starts to behave normally again.

But the "∞" sign comes back after a few minutes of leaving the computer alone.

Related bug: the battery widget CAN'T display only the battery icon. If I uncheck both Percentage and Remaining Time... it displays remaining time anyway.
