I clearly set the trigger to run every 10 minutes, but every 3–5 days, it automatically changes to every 2 minutes.

### Dify version

Version1.16.1

### Cloud or Self Hosted

Self Hosted (Docker)

### Steps to reproduce

### ✔️ Expected Behavior

The trigger needs to be a little more stable.

### ❌ Actual Behavior

However, when I perform the following steps, it returns to normal, but after 3–5 days, the trigger still changes from once every 10 minutes to once every 2 minutes.
sudo docker compose -p dify down
sudo docker compose -p dify up -d

Reproduce the trigger behavior on Dify 1.16.1 in the self-hosted Docker setup, using a 10-minute interval and observing it over several days. Compare the configured interval before and after the reported docker compose down/up restart; done means the trigger remains set to every 10 minutes without requiring a restart.
