Thanks for reporting this. There is a bug when previewing events that have built-in parameters such as distance or cone angle.

It will be fixed in the next release - 1.08.08. Or if you’re comfortable with code you can see the fix on [github](https://github.com/fmod/UnityIntegration/commit/17fc679c5115f3e853ef5bc76c23bef0190821a5)
