Barcodes not being found in WebPOS

struggling to understand why only 4 products appear in the POS when i search the first digits 614 of our barcodes, but we have more than 3,000 products having a barcode starting with 614

Please note that this is a live website, if you do a POS order please apply a note or trash the order.

You can create a cashier user for testing

Here are some barcodes that are used with products within the field called EAN see second screenshot

The weird thing is that for the product Carrot Soap the WebPos is able to find it using the barcode, but all other products using the same barcode field are not getting found by WebPos barcode search
