Pricing table only showing one column

Hi

I have a 4 column pricing table, all content is entered into the pricing table section. In the one-page layout the pricing table is only showing one column

I am using the shortcode:
[pricing_table style=”standard” pricing_item=”300, 307, 308, 329″ columns=”4″ animation=”bottom-to-top” animation_delay=”250″]

thanks
