Mobile view – all posts expanded, menu expanded also

Hi, On mobile all posts on my site seem to be expanded on all pages. So go onto homepage and instead of selecting where to go it is a scroll through whole article and then the next one. Meaning not able to select, also share buttons (plugin) don't show. The menu also, when you click on it all the categories/secondary menu items are expanded rather than just primary menu showing. http://www.thepartialescape.com Using Lucinda, free version.
