Problems with options access on products page.

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1
-- PHP version -- : 5.4.41
-- Browser(s) name and version -- : Firefox

I have set up options in my products page and I have two problems firstly the options are not neat on the page they appear to be cut off.
Secondly when I am logged in (especially in firefox) the options are pushed so far over to the side of the page that they are not active and one can not make out what they are see goo.gl/TXon0g , I have changed the access level to "all" on this page so it is clearly visible.
Can you please help me to get this right?

Just adding to this post - I just found part of the problem was caused by the "Content - Hikashop Social Plugin",pushing things over to one side - I disabled the plugin and the options are more visible but they are still cut off on the right hand side.

Where do I add this css - in the override css?
