Hello,
You use ‘Elegant Tabs for WooCommerce’ plugin that rewrites the tabs file http://prntscr.com/ilrll8
this is default http://prntscr.com/ilrlws
We’ve made changes as explained before, so without the plugin, tabs are closed http://prntscr.com/ilrvcv
Because we are theme support, we can help you with questions that strictly relate to our theme and we do not provide support for 3-rd party plugins.
Regards
