Web Station/Joomla issue, how to increase upload size = Error 500 | Synology Community

I have checked all of the shown php.ini files above and found that all upload_max_filesize set to 32M.

I still has to find the way to change 2M to 32M - see attached screendump taken from here: Joomla-->Extension-->Manage-->Upload Package File

How can you fix that?
