How to fix android manifest.xml naming conflict?

Question

For some reason, even though my app name appeared correctly next to the app icon, when I looked for the app under settings->app, the name appeared to be "libcocos2dx" instead of the correct name.

So I added the following line in my AndroidManifest.xml:

    android:label="@string/app_name"

But it caused the error:

app/AndroidManifest.xml:12:6 Error:
    Attribute application@label value=(@string/app_name) from AndroidManifest.xml:12:6
    is also present at proj.android-studio:libcocos2dx:unspecified:13:9 value=(libcocos2dx)
    Suggestion: add 'tools:replace="android:label"' to <application> element at AndroidManifest.xml:11:5 to override

How can I fix the above error ? I have no idea where libcocos2dx is specified as the name. I am using cocos2d-x v3.7, which uses libcocos2dx.

EDIT: I can see the suggestion to use "tools:replace" , but I feel like I'm masking the problem instead of fixing it. Is there a better way to fix the root cause ?

EDIT: Does anyone know how to add tools:replace ? This might seem obvious to you, but when I add it, I get the error:

the prefix "tools" for attribute "tools:replace" associated with an element type "application" is not bound

Had to add to the manifest header:

xmlns:tools="http://schemas.android.com/tools"

For example:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourpackage"
    xmlns:tools="http://schemas.android.com/tools">

Then in the element:

'tools:replace="android:label"'
