Error message since update 4.3.1

Hi, there is an error message showing on the product edit page since last update:

Notice: Undefined variable: selected_tid in /home/recyborg/public_html/wp-content/plugins/platycorp-etsy-syncer/admin/views/product-edit/class-product-edit-view.php on line 72

It shows at the bottom, close to “Update & Etsy Sync”

So far, it did not caused problems I think.

Thanks
