Hello,
Thanks for your Patience!
This is not an Issue with the Canvas Template but an Issue with IE11 Compatibility Mode. IE11's Compatibility mode degrades the Browser's CSS/JS Support. So you cannot expect a Template using the Latest Versions of all Plugins, Resources and Coding Practices to run smoothly.
To fix this issue, simply add the following code in your Document's <head>:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
or Add the following code in your .htaccess File:
<IfModule mod_headers.c>
Header set X-UA-Compatible "IE=edge"
# <code>mod_headers</code> cannot match based on the content-type, however,
# the <code>X-UA-Compatible</code> response header should be send only for
# HTML documents and not for the other resources.
<FilesMatch "\.(appcache|atom|bbaw|bmp|br|crx|css|cur|eot|f4[abpv]|flv|geojson|gif|gz|htc|ic[os]|jpe?g|m?js|json(ld)?|m4[av]|manifest|map|markdown|md|mp4|oex|og[agv]|opus|otf|pdf|png|rdf|rss|safariextz|svgz?|swf|topojson|tt[cf]|txt|vcard|vcf|vtt|wasm|webapp|web[mp]|webmanifest|woff2?|xloc|xml|xpi)$">
Header unset X-UA-Compatible
</FilesMatch>
</IfModule>
This should fix your issue automatically. Hope this Helps!
