Summary on Energy dashboard of gas consumption with multiple sources

Hi,

I have multiple sources for gas consumption, but their summary is missing when I hover over the mouse. Meanwhile this function works fine with Energy usage.
Is it really missing or my configuration is not the best?

Could we see how you get the summary?

The summary for energy usage is calculated by default, but not for the gas consumption.
Maybe good to mention that I added the measurements using the UI.

Here are the screenshots about it:
