Vue Form Wizard/Generator application blank in IE

[gregvissing]

In IE11, the header and footer show up on this page but not the form I've built. My code: https://github.com/gregvissing/gsv-giving-form/blob/master/giving-form-10-11.html head content: https://github.com/gregvissing/gsv-giving-form/blob/master/giving-form-head-content.html

Application page: https://ucfoun-stg-bbis.concoursehost.com/_2019-giving-page/home

Any help would be greatly appreciated!
