Inslatted Packaga still in Uploaded Packages

Hi

I’ve made a simple package to modify Accounts list view.
After installation of my module everything works OK, but … my package is at 'uploaded packages" not at “installed extensions” so I can’t uninstall

manifest.php

<?php
$manifest = array(
        array(
                'acceptable_sugar_versions' => array()
        ),
        array(
                'acceptable_sugar_flavors' => array()
        ),
        'readme' => '',
        'key' => '342354357743434',
        'author' => 'xxxxxx.com',
        'description' => 'Walidacja i formatowanie numeru NIP.',
        'icon' => '',
        'is_uninstallable' => true,
        'name' => 'NIP formatting and validation',
        'published_date' => '2017-11-02 12:00:00',
        'type' => 'module',
        'version' => 'v1.0',
        'remove_tables' => 'prompt'
);

$installdefs = array(
        'id' => 'mg_custom0001',
        'copy' => array(
                array(
                        'from' => '<basepath>/custom/',
                        'to' => 'custom/'
                )
        ),
        'logic_hooks' => array(
                array(
                        'module' => 'Accounts',
                        'hook' => 'process_record',
                        'order' => 1,
                        'description' => 'NIP format',
                        'file' => 'custom/include/mg_NIP/mg_FormatNipAccountsList.php',
                        'class' => 'NIP_LogicHook',
                        'function' => 'changeNIPFormat'
                )
        )
);

It’s strange. I tried with another SuiteCRM instance and everything works fine. I can install and uninstall package properly.

Maybe there is some permissions problem under the upload/upgrades directory?
