Hi,
If the height consistency script was right called and would be able to do his job, all product blocks would have the same height.
So you wouldn't have responsive issues due to some block smaller than the others in the same line.
Please note that you just provided information using "X" and "O", not a single page or anything which would allow us to take a look and give you a precise answer.
So we are trying to help with the elements with have got. And that's really a few.
But otherwise, yes I'm sure that your problem is related to the height consistency and that HikaShop do not have any Javascript errors in his code.
