"Manage Communities" page "Next Page" link error

Ok, in our dashboard on our WordPress site (WordPress Multisite isn't active) we have the WPMU Dev Communities plugin activated and we have been testing it out so we can use it.

When we have over 10 communities and we go to the "Manage Communities" page it displays the first 10 communities fine, then it has the "Next Page" link above the communities table to view the next lot of communities but when we click on the "Next Page" link the page reloads and the link in the url bar changes but it still shows the first 10 communities....it doesn't show the rest!!

This isn't an issue on the main "Communities" page, only on the "Manage Communities" page.

I need to know if this is an error with the plugin or our website and how to fix it. Can someone help?
