Hello,
There are 228 modified files between HikaMarket 2.1.1 and HikaMarket 3.0.2, including the HikaMarket category helper which handle the display of the namebox.
I don't know the version of HikaMarket that you got before the update (that you were talking about) ; but please understand that we can only provide patches and bug fixes for the latest version of HikaMarket.
If you found the same issue in our demo website (which using the latest version of HikaMarket), we can investigate since we have a way to see and reproduce the issue.
But I am not able to see that issue in my test websites. I can't say if you have an old and fixed bug, if you have a display issue, a bug with AdminTools (or similar) or if you have issues with your Hikashop categories and you need to repair them.
