settings not showing in Magento admin

Question

I am trying to create a custom module in admin but for some reason modules settings are not appearing.
Below is my code.
app/code/Anshu/TrackingImport/etc/adminhtml/system.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <tab id="Anshu_import" translate="label" sortOrder="10">
            <label>Anshu Import Options</label>
        </tab>
        <section id="Anshu_import_section" translate="label" sortOrder="130" showInDefault="1" showInWebsite="1" showInStore="1">
            <class>separator-top</class>
            <label>Anshu Import Options</label>
            <tab>Anshu_import</tab>
            <resource>Anshu_TrackingImport::trackingimport</resource>
            <group id="ftp_credentials" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>FTP Credentials</label>
                <comment>You must enter your live FTP credentials for this extension to work properly</comment>
                <field id="ftp_login">
                    <label>FTP Login</label>
                </field>
                <field id="ftp_password">
                    <label>FTP Password</label>
                </field>
            </group>
            <group id="cron_settings" translate="label" type="text" sortOrder="1" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>Cron Settings</label>
                <field id="expression">
                    <label>Cron Expression</label>
                    <source_model>Anshu\TrackingImport\Model\Cron</source_model>
                </field>
            </group>
        </section>
    </system>
</config>

app/code/Anshu/TrackingImport/etc/acl.xml

<?xml version="1.0" encoding="UTF-8"?>
<config xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/etc/acl.xsd">
    <acl>

                    </resource>
                </resource>
            </resource>
        </resources>
    </acl>
</config>

app/code/Anshu/TrackingImport/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Anshu_TrackingImport" setup_version="0.1.0">
        <sequence/>
    </module>
</config>

app/code/Anshu/TrackingImport/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Anshu_TrackingImport',
    __DIR__
);

It would be great if someone can help me out in finding out the reason and how I can fix it.
