If the parameter DIAG_ADR_ENABLED_listenername is set to ON in the listener.ora file, the parameter log_directory is ignored. The trace and log files are created in the location defined by ADR_BASE_listener_name.you can disable ADR by setting in listener.ora
set the below parameter in listener.ora disable ADR (default is on)

My listener name was LISTENER as "show cur" output above.
