Sadly I can’t just remove it yet, as it is part of the Legenda Theme 2.6.2. It took some work, but after turning everything off and just using the Legenda Theme 2.6.2 and the VC 4.4.3 plugin I could see this conflict in IE 10/11.
If I turn off VC 4.4.3 the entire site breaks due to the VC classes, but that then resolves the I guess a float issue, please test this on your own demo.
Not Sure yet, I will be reporting the same to Visual Composer, thank you kindly for any help that you can offer.
The main issue here, is you can’t checkout in IE 10/11 at all due to this conflict, so we lose customers until this has been solved.
We have checked your site and see that 2-d select does not work even with default theme and disabled Visual Composer plugin. This is WooCommerce problem, update WooCommerce plugin, this problem was fixed.
