I went to update my old SensorPanel design. I the process, I deleted my old graph of current download rate and tried to setup a new one with my new defaults.
If I create a graph, it doesn't show any network rate information on the item list - I only get connection rate and total download. If I do a simple sensor item, it shows up as a selection.
So, I went into Notepad++ in the old exported sensorpanel file that had a working download rate graph, and cut and pasted the graph line for download rate into the new sensorpanel file and the graph shows up correctly in the panel.
It appears whatever config file that determines what can be added to a graph is broken.
I attached a couple of pictures to show what I am allowed to select.
This is version 5.92.4300.
