Displayed error

Plugin version: 1.7.1

I found that in the All product tab, all the product will stuck to the left, bottom side.
But it works fine in others. When the catalogue is empty, the page will go to 404, is it normal ?
The website is in Chinese, maybe a bit difficult for you to recognize the tab.
The first one is “all product”, I did a little changes to make it Chinese. You can find product from the 7th catalog.

I tried to use the plugin to display different store in market to build a review website.

BTW, if you need any help in translation to Chinese, I can help.
