Non-existent energy monitoring feedback

I’m having a small issue with energy monitoring. At first glance, everything seems to be working correctly, but I have two devices for which the data is not being reported.

3 out of 4 are reporting

same, 3 out of 4 are reporting

the one that isn’t working

the one that is working

I don’t really understand why, as the other devices seem to be communicating fine. Does anyone have any idea what could be causing this issue?
