Display all products

There are total 239 products in my SpreadShirt shop, but here only 6 products displays. I have tried different plugin setting but not found any solution.

Shop URL: http://t-shirtsayings.spreadshirt.com/
Website URL: http://tshirt.sharkslab.com/?page_id=40

I have used standard shortcode on the page – [spreadplugin]

And plugin settings are as follows:

Limit articles per page: 15
Image size: 190px
Product category: All Products
Article category: blank
Social buttons: Enabled
Product linking: Disabled
Sort articles by: blank
Target of links: blank
Use iframe for checkout: Opens in separate window
Designer Shop ID: blank
Default display: Articles
Designs with background: Disabled
Always show article description: Disabled
Display price without and with tax: Disabled
Zoom image background color: #FFF
Infinity scrolling: Enabled

Please let me know, how can I display all products? Why pagination not displays on product page?

Thanks in advance.
