Hello, I am getting errors after updating this plugin to the newest version (1.2.2)

Notice: Undefined index: in /home/username/dev/wp-content/plugins/aco-variation-swatches-for-woocommerce/includes/class-acovsw-options.php on line 447

Notice: Trying to access array offset on value of type null in /home/username/dev/wp-content/plugins/aco-variation-swatches-for-woocommerce/includes/class-acovsw-options.php on line 447

When I downgrade the plugin back to 1.1.9 the errors go away.

Hello.

1.) How i can display Swatches on product listing page?
2.) I want the output directly under product image (in listing) is it possible to change position?

Thank you in advance
André
