Good evening Joffrey and welcome back!
Thank you for reaching out to us.
We apologize for the inconvenience caused by this glitch.
We are actively working on a solution for this.
Alas, I cannot guarantee when it will be fixed, as it’s in the development team’s hands now.
They need to assign it, code it, test it, and schedule it for release.
The good news is that you will be contacted as soon as a fix is available.
Thank you for your patience as we see this through.
In the meantime, on our end, we have tested that downgrading to WooCommerce 3.1.2 fixes the issue.
As with any upgrade, it is always better to do a complete database backup first.
Best regards,
Geoff B.
