Why so many bugs and errors? I'm doing a fresh install of this script, expecting it to work normally. But I'm facing many issues that make me can not use this script.

1. The first bug is when creating a product Variation. I create one variation with 4 options. After creating it and saving it. Here is what the system said:

500: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'features' in 'field list' (Connection: mysql, SQL: insert into `products` (`type`, `name`, `secondary_name`, `code`, `symbology`, `category_id`, `subcategory_id`, `brand_id`, `unit_id`, `cost`, `price`, `min_price`, `max_price`, `max_discount`, `hsn_number`, `sac_number`, `weight`, `dimensions`, `rack_location`, `supplier_id`, `supplier_part_id`, `features`, `details`, `file`, `featured`, `hide_in_pos`, `hide_in_shop`, `tax_included`, `can_edit_price`, `has_expiry_date`, `dont_track_stock`, `photo`, `video_url`, `alert_quantity`, `has_variants`, `variants`, `has_serials`, `slug`, `title`, `description`, `keywords`, `noindex`, `nofollow`, `company_id`, `sku`, `updated_at`, `created_at`) values (Standard, Baju Koko, ?, 85421184095, CODE39, 2, ?, 1, 1, 50000, 750000, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 1, 0, 0, 0, 0, 0, 0, https://domain.id/asset/images/products/XbkhowflrBe7ex9iaXleAcjO1ItAUlhQPt25vsNQ.png, ?, ?, 1, [{"name":"Warna","options":["Merah","Biru","Pink","Hijau"]}], 0, baju-koko, Baju Koko, ?, ?, 0, 0, 1, 01k3fah2x4w2z91vvckjasncxm, 2025-08-25 00:37:24, 2025-08-25 00:37:24))

2. The Second Bug is when adjusting the variation product. You can not adjust this type of product. The dropdown when you press the data it's only stuck like that. This bug has not only happened to me, but also on your version 4 demo, too.

3. Barcode issue: When I scan the item in the cart, it creates a duplicate item. Please see the video
