WPML widget not displaying like expected in Internet Explorer

Hi there. I need your help with a very important issue regarding WPML widget. When I try to visit the site in Internet Explorer 10 it’s not showing how it should.

This is how it looks in Chrome /Firefox (The right way)

This is how it shows in Internet Explorer (Wrong)

This is the actual css code I’m using to control the widget as adviced by one of your team mates.

.avia_wpml_language_switch {
max-width: none;
width: 225px;
}
.avia_wpml_language_switch li span.language_translated{
display: block;
float:left;
padding-top:2px;
}
.avia_wpml_language_switch li .language_flag {
display: block;
float: left;
}

Which CSS lines should I add to correct this? Many thanks in advance guys.
