The energy (kWh) sensors feed the history and the charts, but the instant values need a power (W) sensor on each source.
In your Home Assistant Energy dashboard, add the optional power sensor to each source, not only the kWh one. Without it the chips have no real-time value and stay on a dash, while the history and the curves keep working thanks to the kWh sensors.
No power sensor from your hardware? You can create a virtual one with a Derivative helper on your kWh sensor. It gives a value in W that is not exact to the second but works very well in practice, and you can then add it to that source in the Energy dashboard.
