FMOD Studio has a[Localized Audio Tables](https://www.fmod.com/docs/2.02/studio/dialogue-and-localization.html#localized-audio-tables) feature, which will produce a separate bank for each language being used - the example project has three localized banks. By default, the FMOD for Unity integration loads all bank (which you can see in the Initialization section of FMOD Settings in Unity), so these two warnings are being produced by the integration trying to load two of the localized banks after alrea…

From the code you shared, it seems that the `dialogueCallback` is declared but not assigned to `DialogueEventCallback`. Without this assignment, the callback won’t execute as expected.

To resolve this, please assign the callback in the `Start` or `Awake` method like this:

```auto
dialogueCallback = DialogueEventCallback;

```

Hope this helps, let me know if the issue persist.
