question about saving
Hi, Could You to help me.
Settings in the rules are not saved (see screenshot) [

After execution, save and apply fields become empty

I have the Similar problem.
I performed transformations such as "Merge" and "Group By". But I can only select "undefined" on "apply to metrics" menu of flowcharting.
It seems to work well when I select "undefined" and procced. But, When reloading the page after saving, it encounters "Blank" on "apply to metrics" field and does not work.
If you know a solution to this issue, please share it.
My Grafana v7.3.7 (1e261642f4) Flowcharting version - 0.9.0 Datasource - Json API
