Overrides being ignored when standard settings -> displayname is set

### What happened? I query data from InfluxDB and use overrides to fix units, display names, etc, per measurement. For some reason, my overrides get ignored when the display name in fieldconfig is set to anything but an empty string. When the displayname is set to an empty string the overrides works again. ### What did you expect to happen? THat the overrides would be respected ### Did this work before? Don't know ### How do we reproduce it? 1. We want a separate table per measurement. For the influxquery, use: from(bucket: "bucket") |> range(start: v.timeRangeStart, stop: v.timeRangeStop) |> filter(fn: (r) => r["_field"] == "Value") |> filter(fn: (r) => r["_measurement"] == "a" or r["_measurement"] == "b" or r["_measurement"] == "c") |> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false) |> keep(columns: ["_measurement", "_time", "_value"]) |> yield(name: "mean") 3. Define overrides for the measurements and see them take effect 4. Standard options -> DisplayName: set this to anything but an empty string, and see the overrides are not applied anymore ### Is the bug inside a dashboard panel? | Key | Value | |--|--| | Panel | timeseries @ 12.2.1 | | Grafana | Grafana v12.2.1 (563109b696) // Enterprise | <details><summary>Panel debug snapshot dashboard</summary> ```json { "panels": [ { "id": 2, "type": "timeseries", "title": "Reproduced with embedded data", "gridPos": { "h": 13, "w": 15, "x": 0, "y": 0 }, "fieldConfig": { "defaults": { "custom": { "drawStyle": "line", "lineInterpolation": "linear", "barAlignment": 0, "barWidthFactor": 0.6, "lineWidth": 1, "fillOpacity": 0, "gradientMode": "none", "spanNulls": false, "insertNulls": false, "showPoints": "auto", "showValues": false, "pointSize": 5, …
