Hi Gaetan,
try update the column "VariantGroupUnit" with all rows setting to zero "0" in the table [EcomVariantGroups] and restart the web site.
For showing the variants it is needed to fill the table [EcomVariantgroupProductRelation], but it is not availble directly in the EcomProvider(it fills it on the information from EcomProducts VariantOptions and VariantGroups columns).
For importing variants with EcomProvider it is needed to use the columns "VariantOptions", "VariantGroups" in "EcomProducts" table and filling the values with comma separator,
fx for "VariantOptions": "VO1,VO2". It can be variant option id or variant option name, the same for variant groups id/name.
You can read more about this columns here.
Maybe this can help if you need to use the Dynamicweb provider.
Regards, Dmitrij
