Sorry for the delay getting back to you, Luo is on vacation and we have a couple of unexpected absences which are leaving us a little short.
I just checked this myself and was able to reproduce it. You can see the difference between the front end and back end in the screenshots.
Please bear with me a little longer to prepare the internal tickets, now that I've confirmed it I'll share it with the developers and escalate this thread.
I'm pleased to say the fix for this is now available.
You can find the plugin updates available from your downloads page, or on your site if you don't see them available on the plugins page, use the "Check for Updates" button on the custom installer page.
