Hey Matthew,
Thanks for reaching out to us and also for providing the video to help clarify the issue! Definitely helpful.
I did some testing and wasn’t able to replicate with WooCommerce core plugin being the culprit. I noticed that you had several WooCommerce add-ons as well. Since the code for those shouldn’t fire unless WooCommerce is active, by deactivating WooCommerce you’re essentially deactivating all of the WooCommerce specific add-ons as well.
Try leaving WooCommerce active and the deactivating the WooCommerce specific add-ons to see if it is one of those that is causing the issue rather than the core plugin.
Thanks!
