Errors when I try make a mesh group from fbx. Not sure what the errors means.

Getting errors like - Invalid normal data detected at index 6070 and Component type AzStdReflectionComponent not reflected to SerializeContext!

I have no idea what these mean and have been scouring the documents for answers. I’ve looked at my mesh in maya to see if i have any wierd vertex normals. Have deleted history. I just have bones and one mesh within the fbx file. I also have the DCC custom normals checked.
