Hi,

1. Please provide a backend access and a link to that thread via our contact form so that we can have a look at the issue.

2. Please open a separate thread in the hikamarket forum section for issues relative to HikaMarket. Also, this issue is likely linked to the CSS of your template. But hard to say precisely without looking at the problem. So I would recommend to provide a test vendor account and the necessary instructions to reproduce the issue when you create the thread in the HikaMarket forum section for that issue.
