Events List paging is odd

I have an events listing (http://www.isciencemag.co.uk/events/), which shows page 1 of my future events.
– If I left-click on ‘next events’, I get ‘There were no results found’.
– If I right-click and choose to open in a new tab, the next page is shown correctly (and the same happens at the bottom of this page)

Any suggestions welcome!
