Group options with product does not always work

if I add a product (which has product options) to the cart, but do not select any option (all options are set to "no")

and after

I add the same pruduct with a select option. the 2 product will not be grouped (i have enabled [Group options with product])

When I do the same conversely. 1) product with an selected option and 2. the same product with no option, it works

see attachments

Hi,

I just tested it on my end and it seems to be working fine, so can you download the last Hikashop version, install it and test it again ?

same issue with the actual version

you have PM

Problem solved! many thanks.

The system does not summed products with options - it lists it separately.

I think this is OK:
- Products without options are summed.
- Products with options are listed separately (even if the same options were selected).
