[Plugin: The Events Calendar] Import function not working – and date input won’t hold the date for

Hi,
I’ve installed The Events Calendar and the Eventbrite plugin to go with it, but when i click “import an existing event from Eventbrite” nothing happens.

Also, when i try to do it manually, it gives multiple drop-downs for the Start and end dates – and although it’ll pick up the right month, it won’t “hold” the dates – it just keeps defaulting to the 19th.

This is very weird! Please help!
