Bugs in content types

Whenever I use the export-function in the course presentation in Safari (macOS Sierra 10.12.1) I just get a textedit-document, which is impossible to open. In Chrome (on the same computer) it exports as a .doc-file. I haven´t tested it with other browsers. 

Can this be fixed?

I'm using a course presentation on our WordPress site, and am having an issue.  Every time I try to close out of an icon interaction it throws me to the bottom of the page.  Any help is greatly appreciated!  http://www.g51edu.com

Thanks,
