Remove prefix value of Manifest com.facebook.sdk.ApplicationId

Hello, I'm trying to integrate the Facebook SDK in my Unity project. I'm going through the Quick Starts process, and I'm asked to add a meta-data to my manifest file with "com.facebook.sdk.ApplicationId" and the app id as a variable from the strings.xml file.

However, the manifest already has that meta-data, but with a value that looks like "fb0000000".
