Flip-box and Ie 11

Hello! We have recently implement Site-Origin’s awesome Flip-Box widget on our homepage.

Everything is working as expected in Chrome (and even Edge) however in IE 11, the flip-box does not show the backing on flipping and instead just vanishes.

Can anyone suggest why this might be occurring in IE11 and how it might be fixed?

You can see the issue on the following page www.gaconsulting.co.kr (the widget has been used for the 6 banners under the red bar with the Koala).

Any advice you can provide would be greatly appreciated.

Thanks!

Matthew
