Discount amount not applied to first product id in discount

-- HikaShop version -- : 3.4.0

Hi,

When using discount on product with variants, choosing when adding product only "all variants" for each product, the first product in the discount dont got the amount applied:

Discount type : discount
Discount percent amount: 50
Discount code : discount-50
Discount product id : 2 or 100 to the same

screenshot of the settings of the discount

• discount-1.PNG
• discount-2.PNG
• discount-3.PNG

• discount-product-1.PNG
• discount-product-2.PNG
• discount-product-variant-1.PNG

• discount-front-1.PNG
• discount-front-2.PNG

- If the first product of that list doesn't have variants, do you still have the problem ?
No, setting another product without variant in first position fix the problem

- do you have the problem for all the variants of that product on the product page ?
Yes

- do you have the problem on the cart/checkout as well ?
Yes

do you have the problem with the default template of joomla too ?
Yes

But, when doing thoose test, when editing a discount, adding a product, saving then removing and saved again fixed the issue ..., so i tested on another discount: open and save fix the issue

All of discount was imported via phpmyadmin via CSV, maybe the issue is here :

When saving, the field "discount_product_id" in the table "#_hikashop_discount" add "," in first :
After import and before saving from backend = 1,2,3,4,5,6,7,8,9,...
After saving from backend = ,1,2,3,4,5,6,7,8,9,...

And some field a change see attachments (line 1 = after saving discount from backend and line 2 after import from db)
In my CSV for import discount, i only fulled thoose fields : discount_id,discount_type,discount_percent_amount,discount_code,discount_published,discount_product_id,discount_currency_id,discount_tax
