Hallo! Welcome to Core Trac.

Trac is meant for reporting WordPress Core issues (Core Trac) or issues with the WordPress website (Meta Trac).
The good news is that all plugins hosted on WordPress.org have their own support forums, where those communities can help one another.
You can find the one for WooCommerce here: ​https://wordpress.org/support/plugin/woocommerce/

I am closing this ticket as "invalid" here for this team's workflow purposes.
That does not mean that it isn't a valid question, just that we can't do something about it here :)
