I would recommend hiring someone professional as I went through the same problem while uploading amici violent jacket. It got better with professional help. 

But i have changed some HTML structure for my market grid loop. when i visit brand it was different. I mean rehub original loop page not my changes one.

I guess there is another loop design working. it should be am option on rehub theme to change brand page design too.

it must follow design of archives which you selected in theme options - shop settings

Hi,
