Passing array to component, devtools sees it, the component does not - vue.js

Question

I'm passing an array to a component but the component sees the array as undefined. Here is the parent calling the component...
<FileList ref="files" class="ma-3 pa-0" :passFiles="true" :passedFiles="header.files"></FileList>
Vue devtools sees the array, it is valid. As seen in the screenshot below:
Yet in my created hook in the controller, it shows this.passedFiles as undefined. (this.passFiles, however, shows correctly as true.)
created(){
console.log(this.passFiles,this.passedFiles); //this.passedFiles shows as undefined
window.addEventListener("resize", this.onResize);
},
I dumped the array right before it gets sent to the component, and it is there, see screenshot:
I tried this just to make sure, and it gets passed to the array fine:
:passedFiles="[{0: '1'}]"
I'm pulling my hair out here. Here is the full component, it is long but it shows you everything
