Subcategories in content module wont show product

-- HikaShop version -- : 2.3.0

Hi

I'm having problem with showing the subcategories products, when I click on them in the Hikashop content module.

When I click on the main category, in the content module, and click a subcategory in the content area, the products are getting shown without any problem.Also with a better url.

The other problem is double content, and two different urls to the same category and product.

When I click Læderarbejdshandsker in the subcategory, in the content module, the url looks like this:

handske.webskraedderen.dk/index.php/comp...shandsker?Itemid=788

And nothing is getting shown, but a blank page.

When I click the main category Arbejdshandsker in the content module on the left, and then in the content area click on Læderarbejdshandsker I get this url:

handske.webskraedderen.dk/index.php/kate...aederarbejdshandsker

And the product in the category is getting shown just fine.

What seems to be the problem here? And what can I do to correct it. Its not good with double urls to the same product, not good for SEO.

I know that there is a canonical feature tried it on the category level, but it did not work. And why is component/hikashop in the url. Many questions to be answered, but I hope anyone can help.

Best regards
Ivan
