Frontend download for options

-- HikaShop version -- : 5.1.5
-- Joomla version -- : 3.10.12
-- PHP version -- : 7.4.33
-- Browser(s) name and version -- : Firefox 136.0.2

I have a product with Options. I also have different serials (images) for main product and for Optional product. In backend i can see and download both different serials (boarding passes in my case), but in frontend there is only one for download, whether in list i see both serials, but for downloading iamges available only one - main product serial.

Also in emails. Attached there are both serials, but there is a link for downloading them and the link only for one serial - main product's serial.
