Variant names not saved when changed

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 4.0.2
-- PHP version -- : 7.4

Hi there,

I think I found a bug in Hikshop and J4.
When I change the name of a variant and save it. Nothing is saved. When I go back to check, the name field is empty again.

With kind regards,
