Store doesn't show up on microsoft office 2016 for mac

I can type a URL directly into the document, it's converted to a hyperlink, and works perfectly.

This is only an issue in Word - hyperlinks created the same way in Excel work normally. Hyperlinks created using the Insert Hyperlink tool are not opening at all.

I'm deploying Office 2016 as part of a Windows 10 SOE update, and I've run into a problem I'm having trouble solving.
