Problem with translation and variant title devider

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 4.0.2 and 3.10.1
-- PHP version -- : 7.4
-- Browser(s) name and version -- : Chrome

Hello,
I've just installed Hikshop 4.4.3 on a Joomla 4.0.2 site and noticed something wrong with de variant titles. Tried it on Joomla 3.10.1 with the same result. I used Cassiopeia and Protostar.

When showing a variant it puts the text 'HikaShop varianten scheider' where the : should be.

It only does this when I set the site to Dutch.
But I can not find where to correct this (in language file of elsewhere).

Hope you can point me in the right direction (and fix it for future installs).

With kind regards,
Rachel Walraven
