Let's perform some troubleshooting to check if this is a browser issue.
First, try viewing the Save and send button in incognito window. This way, we can rule out if this isn't any cache related issue. Here's how:
Google Chrome: press Ctrl + Shift + N
Internet Explorer and Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
If it works fine, go back to regular browsing and clear the browser's cache. You can also try using a different browser (Internet Explorer, Chrome or Firefox).
