It's possible that:
* The spelling is slightly different. Could you double-check the spelling?
* She goes by a different stage name. Do you know any other names she might use?
* She is relatively unknown. It's possible she has worked on smaller projects or is just starting her career.
To help me find information, could you please provide any additional details you have about Kate Melton, like:
* Any approximate age or years active in the industry?
* Any specific genres she might work in?
* Any other roles she has had, even if they are small?
With more information, I can hopefully help you find the projects Kate Melton has been in.
