Barking zippy

Hi all, completely new to bike owning, bought my 2012 ybr yesterday, and checking it over today I notice the centre when up rubs against the chain, it's not supposed to (obviously!) but I am not sure what's not working or missing to allow it to do that, anyone got a similar bike and could have a quick look and let me know? The exhaust cover was removed along with some of the wields and brackets, I wonder if there's supposed to be something on there to block the stand from going up that high so it touches the chain on the other side? cheers!
