WooCommerce shortcode "orderby" has no effect on order

I’m putting together a page where people will be able to “Tip” one of 100 chefs. I’m using the shortcode

[product_category category="tips" per_page="100" columns="4" orderby="title"]

to list all the “products” in the category “tips.”

That part works fine, but no matter what I put in orderby-"whatever" the products are always listed by the date they were created.

I’m guessing there must be some kind of conflict with the theme I’m using, but I have no idea where to start looking to identify where the problem is.

View the page at https://100menelkhart.flywheelsites.com/?page_id=150.

I need to point our domain to this site tomorrow, so any advice would be a great help.

Thanks!
