Parsing XML Error Duplicate Atrributes

Question

I've tried so many solutions I've about given up with it. I'm getting two xml parsing errors that keep popping up after cleaning the project, making a new project, or re-importing the project. Nothing seems to work. It has to do with the layout xml and some data binding xml of the same name but it just keeps loading the data binding xml that's in the build folder and it seems a debug location and giving me the errors.

Here's my layout xml:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable name="user" type ="com.example.chave.utclinicalnursing.signUpActivity"/>
    </data>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
