Where did you add the "phpinfo" file to get this information?
As you can see here, the "master value" matches with the one you specified in the php.ini file. However, the local value is the value of the parameter after reading all the configuration files. That means that somewhere in the code you are specifying 128M for those parameters. If you deployed a custom PHP application on top of LAMP, please review its configuration. For example:
sudo egrep -Ri 128M
or you can also run these commands
sudo egrep -Ri post_max_size
sudo egrep -Ri upload_max_filesize
