"Facebook (build 140579)" In Notification Shade

Today, I'm not sure exactly when, a notification appeared in the notification shade on my Galaxy Nexus that reads "Facebook (build 140579)" and appears like a never-ending update. It cannot be swiped away or expanded. It's not a very large issue it is simply annoying and confusing. Does anyone else have a similar issue and/or know of a way to fix this?

Here's a screenshot:

I've tried rebooting the phone and uninstalling and reinstalling the Facebook application but neither have worked. I'm hoping somebody may be able to help.

That is all.
