How to get controllers to show when you already have a glb importer in your project.

[imjusthere]

When installing MRTK3 you click to fix several warnings in the project validation tool. One of them says if you already have a glb importer not to fix it. Since I already have a glb importer (from the Ready Player Me package) I didn't fix that warning. I can see the left GLB model and it looks correct if I put it in the scene view. What doesn't get loaded correctly is the LeftControllerModel prefab. It says "missing" and there is no hierarchy inside it. I am guessing that is why no controllers show if I run it. If I have both importers I get the error below and the controllers still don't show I'm assuming because of the error. What can I do about this?

Multiple scripted importers are targeting the extension 'glb' and have all been rejected: Siccity.GLTFUtility.GLBImporter (assembly: C:\Users\Chris\Documents\Unity Projects\MRTK3SetupTest\MRTK3TestSetup\MRTK3TestSetup\MRTKDevTemplate\Library\ScriptAssemblies\Siccity.GLTFUtility.Editor.dll), GLTFast.Editor.GltfImporter (assembly: C:\Users\Chris\Documents\Unity Projects\MRTK3SetupTest\MRTK3TestSetup\MRTK3TestSetup\MRTKDevTemplate\Library\ScriptAssemblies\glTFastEditor.dll)
