"No data for selected query" in Explore Tempo menu

[eunhwa-park]

Hi, I’m trying to use the Explore Tempo plugin. I've connected the Tempo data source, and traces are visible, but in the RED metrics or other sections, it shows "No data for selected query." There are no errors in the logs of each pod either.

• Tempo App version : 2.6.0
• Tempo Chart : tempo-distributed-1.18.4

What could be misconfigured? Below is the values.yaml file.

Thank you!
