Steps to reproduce:

1. Add a Graph (new not classic) to the dashboard
2. Add a data source that comes from an auto discovery rule
3. Instead of adding the one selected, ALL auto discovery elements will added with $1 in the name

Result:

I have a firewall with port auto discovery rule. I want to add one ethernet port, but they are all listed as this

instead of the names seen in eg "Latest Data"

And then the graph is pretty much useless

Expected:
I want to see only the source I selected and not all of them
