When multiple bands plotted, bands has a unexpected rigid shift

[unkcpz]

When I plot two bands which has a shift in fermi level, the bands are not aligned properly, as shown below. You can find the exported JSON below and the fermi level is different but since it is a metal, the bands should aligned in terms of fermi level.

Is that possible in widget, only one fermi level is used rather than the bands are shifted to 0eV by substracting the fermi energy?

Here is the JSON file, exported from the widget:
bandData0.json.txt

bandData1.json.txt

It is not hard to implement one Fermi level to algin for all bands data. However, the question is whether we want to do this since we can easily modified the JSON file Fermi energy value.
