Remove Shopify Pre-Order Warning

I use the BYOB (Build Your Own Bundle) app on my Shopify store, which only sells physical products and should never display any pre-order notices. Right now, a “Pre-order / insufficient inventory” warning is appearing on the bundle page and in the cart even though no item in my catalog is (or should be) inventory-tracked. BYOB’s support insists the alert comes from Shopify, while Shopify points to a product that supposedly has inventory tracking enabled—yet I can’t find any variant with that setting turned on.

Here’s what I need:
• Track down whatever product, variant, or bit of theme code is triggering Shopify’s inventory check.
• Disable inventory tracking for it (or for the entire store, if that’s quicker) so BYOB no longer receives or passes along the warning.
• Confirm the fix by adding a bundle to the cart and showing that the pre-order message is gone in both the bundle builder and checkout flow.

The theme does include a small customization (“Product Variants in Table”), but there’s no dedicated inventory app installed, so the culprit is likely a hidden setting, leftover metafield, or a line of Liquid. If you’ve untangled similar Shopify/BYOB conflicts before, this should be a straightforward task. I’ll provide collaborator access as soon as we agree to proceed, and I’d like to wrap this up quickly.
