Grafana 8 breaks Data Link variable to be "results"

Grafana Configuration
1

Grafana Version : v8.0.6

I was using Graph Visualization. When I upgraded to grafana 8, it no longer passes the column variable correctly. Following is my data link:

/d/mongodb_dynamic/mongodb-detail?var-column=${__series.name}&from=${__from}&to=${__to}

Expected URL picks up the series name:

http://.../d/mongodb_dynamic/mongodb-detail?var-column=limit

Actual URL (Broken) The value is changed to “results” for some reason :

http://.../d/mongodb_dynamic/mongodb-detail?var-column=results
