Grafana sidecar preloading dashboard unable to load in the right folder - Stack Overflow

I have below helm charts. Grafana chart version: 8.8.1. I'm trying to preload the dashboard test into the folder Common. But the result is the dashboard test showed up under the root directory, the folder Common also showed up but empty. How do I load it into the folder?
