That was the issue, or at least part of it.
I had all the posts already created when I add the radio button to my order_block ACF group and for some reason, it just stopped passing the value: thought maybe it was naming (product_category); thought it was because all the posts already existed…
As soon as I changed it to a checkbox, everything came back, so I’m not really sure what’s going on.
Thanks for the quick response and great plugin! Nice parallax btw!
