Java EE duplicate info on same log line

Question

I want to use log4j2 version 2.17.1 with wildfly 15. I did all that was written here and here but it isn't fully working.

My issue is that for the stdout logs, some information (like date and level) is duplicated on the same log line.

09:48:48,810 INFO  [stdout] (default task-1) 2022-03-07 09:48:48,810 [default task-1] INFO  com.happypanda.rest.DashboardResourceImpl - Calling getDashboard with parameters: filter=null; order=null; offset=null; limit=null

I need only console logging. I tried to exclude the logging system but no success so far. I still see duplicates info on same line

standalone.xml configurations:

<system-properties>
    <property name="log4j.configurationFile" value="${env.JBOSS_HOME}/standalone/configuration/log4j2.xml"/>
</system-properties>

<subsystem xmlns="urn:jboss:domain:logging:6.0">
    <add-logging-api-dependencies value="false"/>
    <use-deployment-logging-config value="false"/>
    <console-handler name="CONSOLE">
        <level name="INFO"/>
        <formatter>
            <named-formatter name="COLOR-PATTERN"/>
        </formatter>
    </console-handler>
    <periodic-rotating-file-handler name="FILE" autoflush="true">
        <formatter>
            <named-formatter name="PATTERN"/>
        </formatter>
        <file relative-to="jboss.server.log.dir" path="server.log"/>
        <suffix value=".yyyy-MM-dd"/>
        <append value="true"/>
    </periodic-rotating-file-handler>
    <logger category="com.arjuna">

    </logger>
    <logger category="com.github.tennaito">

    </logger>
    <logger category="org.jboss.as.config">

    </logger>
    <logger category="sun.rmi">
        <level name="WARN"/>
    </logger>
    <root-logger>
        <level name="INFO"/>
        <handlers>
            <handler name="CONSOLE"/>
            <handler name="FILE"/>
        </handlers>
    </root-logger>
    <formatter name="PATTERN">
        <pattern-formatter pattern="%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n"/>
    </formatter>
    <formatter name="COLOR-PATTERN">
        <pattern-formatter pattern="%K{level}%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n"/>
    </formatter>
</subsystem> 

log4j2.xml location is under /standalone/configuration

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="ConsoleAppender" target="SYSTEM_OUT">
            <PatternLayout pattern="%d [%t] %-5level %logger{36} - %msg%n%throwable"/>
        </Console>
    </Appenders>
    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="ConsoleAppender"/>
        </Root>
    </Loggers>
</Configuration>

What are the correct locations for jboss-deployment-structure.xml file? I tried WEB-INF, META-INF and resources.

It's even possible to use log4j2 to log stdout in wildfly?

Later edit:

I added the following config to standalone.xml file:

<console-handler name="stdout" autoflush="true">
    <level name="INFO"/>
    <formatter>
        <pattern-formatter pattern="%s%n"/>
    </formatter>
</console-handler>
<logger category="stdout" use-parent-handlers="false">
    <level name="INFO"/>
    <handlers>
        <handler name="stdout"/>
    </handlers>
</logger>

I see the same duplicate information on the same log line.
