Product name doubles up when variant is selected

-- HikaShop version -- : 3.2.2
-- Joomla version -- : 3.8.3

Hi There,
Something strange started happening to our products name. I think it was after the latest stable update but I can't be sure as I just noticed it.
Products with variants, when I select a variant from the dropdown it doubles up the product name instead of showing the variant size.
I removed my template overrides to ensure it wasn't an issue with the overrides. But even when it is not using the overrides it still duplicates.

Any idea how to resolve this?
The goal is to display the product name and then the the variant is select it show the variant title/name.

Thanks

Thanks Nicolas,
I will try to get you an staging link.

Edit:
I see the variant uses the same name as the parent in our case so it is easy to locate the products and variants in a spreadsheet.

So my question is, is it possible/how could I display the variant selected value instead of the variant title.

For example:
Main Product: Moving Boxes
Variant name: Moving Boxes
Variant selection: size 2
Variant selection: size 3
Variant selection: size 5

At the moment, when a variant is selected from the dropdown, it displays the title
Moving Boxes: Moving Boxes

How could I show the selection rather than the variant title? so it would look like this
Moving Boxes: size 3

Please note I don't want to rename my variants, I want to display/append the selected value instead of the variant name.

thanks

Thanks for the response Philip, I was hopping there would be a way to not have to change every variant name.
Is there something I could change in the template override to display the variant value instead of the name?

Thanks again

Thanks for pointing me in the right direction Nicolas.
Done that, all work fine now.
Cheers
