Fix Product Quantity Display Bug

I’m running Stock Manager Advance 4.0 (Laravel + Vue) that I bought on CodeCanyon. Everything worked fine until I deleted one supplier. Since that moment, whenever I open the Products page for any store the quantity column shows nothing—yet the figures are still present in the database. What I need • Investigate why the quantities vanish only in the admin panel after a supplier record is removed. • Restore normal behaviour so that, when I click on a product, I once again see the full, detailed product information including the correct on-hand quantity. Context you may find helpful • Issue began immediately after the supplier deletion—no other changes were made. • The codebase is straight from the original package; I have not added custom code or third-party modules. • Database tables and values look intact, so the problem appears to be in the application logic, model relationships, or a Vue component that now receives empty data. Deliverable A patched version (or clear code diff) that brings the quantity display back, along with a brief note of what you changed so I can replicate it in staging and future updates. i will give you access if you are on board
