Hi,
Well, it's hard to give any solution as we would need more information for that.
Here is what I can say for now:
- looking at your first screenshot, it doesn't look like you're using the Joomla search module or the HikaShop filter module for your search but something else. Does it support the plugins of the group "search" of Joomla ? If so, how did you configure the HikaShop products search plugin settings ? Could you provide a screenshot of its settings ?
- looking at your second screenshot, it looks like an alias issue. Could you provide a screenshot of the settings of a product with the issue (for each issue), a link to the website, and precise instructions to reproduce each issue ?
If you want to provide that information privately, you can use our contact form:

Make sure you include a link to this thread in your message.
