config.php gets overwritten with old config-style, when using the GUI to make changes to it

[inDane]

Hey there, I've upgraded my old BookedScheduler Instances with the newest git version. In the upgrade process I had to convert the old config files to the new style like this:

<?php

mysqli_report(MYSQLI_REPORT_OFF);
error_reporting(E_ALL & ~E_NOTICE & ~E_STRICT);
//ini_set('display_errors', 1);
//ini_set('display_startup_errors', 1);

/**
 * Application configuration
 */
$conf['settings']['app.title'] = 'LibreBooking';            // application title

So far so good, everything seems to work just fine; unless I am trying to change the config.php via GUI. If i change anything and press "Update" it will then revert to some old-style version of the config.php and breaks the page.

Is this a bug or did i miss anything while upgrading?
