wrong appearance of switchs on administrator page

-- HikaShop version -- : HikaShop Business: 2.3.2
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.4.31
-- Browser(s) name and version -- : Mozilla
-- Error-message(debug-mod must be tuned on) -- : no

here is you can see that swicthers in the backend is shown wrong. On the right side the standard view of Joomla switchers

<fieldset id="config_store_offline" class="radio btn-group">

I have repeated this on many sites with clear installation of joomla and hikashop
on every site and every browser I have the same result

here is my display

and this is the firebug that can proove that always ok with your backend.css but it doesn't display well this buttons

but if I try to switch to English language - all is working OK


So I think that problem with Russian language file. Could you help to fix the problem?

the problem is with css file that russian administrator panel turn on

this line will help

fieldset.btn-group label.btn {padding: 4px 12px;}
