Error Notices

Hey!
First off I wanna say: Awesome plugin! ??

It’s working perfectly fine for me, but I just wanted to let you know that I’m getting some error notices.

On pages I get:

Trying to get property of non-object
 Type: PHP Notice Line: 120
 File: /content/plugins/taxonomy-filter/taxonomy-filter.php

In the admin I get:

NOTICE: /content/plugins/taxonomy-filter/taxonomy-filter-bulks.php:179 - Trying to get property of non-object
include('wp-admin/edit-form-advanced.php'), require_once('wp-admin/admin-header.php'), do_action('admin_head'), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, taxonomy_filter_admin_hide_bulk_columns_css

and

NOTICE: /content/plugins/taxonomy-filter/taxonomy-filter.php:174 - Trying to get property of non-object
include('wp-admin/edit-form-advanced.php'), require_once('wp-admin/admin-header.php'), do_action('admin_head'), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, taxonomy_filter_add_boxes

Have a good week!
