1. Is this request related to a challenge you're experiencing? Tell me about your story.

There is a major bug in Dify. If you have deployed the TTS A model and then want to switch to another TTS B model, it keeps looking for the old model TTS A, which I have either disabled or deleted, and cannot automatically switch to TTS B. There is also no place to specify this.

2. Additional context or comments
