Migrating Log4j1 to Log4j2 for Spring 3 + Java8 App, but some logs are only printing on Console instead of Log file, what is missing

Question

I have to migrate an old Java 8 app from Log4j 1.x to Log4j2 due to vulnerability, application is running fine without issues but logs are not appearing properly in log file.

This is the old log4j.xml file.

Not sure what is missing/wrong in the log4j2 file but some logs only appear in Console and not in log file even though I am expecting exactly opposite.I have configured Console for only Error messages, and log file to contain messages like Info,Debug. I am clueless, can someone help here?

Note: @LOG_DIR@/@LOG_FILE_NAME@ - These variable values are replaced during build time.
