"Substance plugin missing" pop-up on iphone?


I launched my game on my iphone, and when it starts, there’s a popup window on the phone stating that I need the substance plugin for this project. I’m like wtf?!?!? for many reasons:
1.The substance plugin IS installed.
2. I DON’T use it in this project.
3. The popup appears on my PHONE.

Can somebody help me out?
