Vimeo video duplicate images, javascript errors

Version 2.1.0.1
We are having problems with Vimeo videos as part of units. The image seems to be repeated twice but overlaps following text on the page covering it up. See screenshot.

We also find there are JavaScript errors on the page viewing preview on Chrome Version 59.0.3071.115

"Uncaught TypeError: Cannot read property 'value' of undefined
at i (video-vimeo.min.js?ver=2.1.0.1:1)"
The links are in the plugin at coursepress/2.0/asset/js/external/video-vimeo.min.js?ver=2.1.0.1
