Tooltip in Times Series contains `{name="Alias"}` instead of `Alias`

I’m using grafana v9.4.7

I’m trying to display metrics from Opensearch/Elasticsearch. In the old Graph, everything worked as expected but with the new Time Series, the tooltip is strange.


Instead of pure Alias, the {name="Alias"} is displayed.

If there is only one metric, the tooltip name is displayed correctly. In some rare cases, the tooltip will also display correctly in this panel. Wrong tooltip will return after changing e.g. the time range.

I tried this with both Opensearch and Elasticsearch data source with the same result.

Is there some configuration for Time Series panel where I can disable this or is it a bug?
