Hi,
The problem is that the title of the product does not allow to be displayed on several lines.
So it uses a larger size and increase the width of his container. So the result is not something expected.
I think you have a CSS rule which forbidden the "word wrap" or something like that.
But it's not something in the HikaShop CSS file.
