Vendors Can't See 'products That Vendors Can Sell'!

All products are common to vendors. Everything was fine a few days ago- not vendors can only see the products they already have listed in their store. "Products that vendors can sell" come up with nothing available!

I can see them on admin.

The only thing I've done in the past few days is clean up the categories/subcategories. But everything is showing up fine on my end, and all active products in the vendors' stores are working well.

Thank you in advance for any help with this!

Have you upgraded your store up to 4.14.2? They changed the Common products add-on there
