[BUG] list and graph are not consistent

[bartplessers]

Describe the bug

I use

• RPI, raspbian, buster
• docker
• hass.io in docker
• zigbee2mqtt addon
• Z2MA addon

When I take a look at the graph, I have 10 orphaned items:

It's not only one device that is different, both lists are different:

It is not very consistent, sometimes I have even more differences

Expected behavior

Same info in graphical view and in listview
