Update Notifications 2.1.3 Needs Update

FYI: After updating to Update Notifications v. 2.1.3 the version does not update in the WPMU Dev Updates tab. I confirmed the correct files got uploaded, and both the plugin file and changelog indicate v. 2.1.3 but 2.1.2 is still listed under Updates, with the note to update to 2.1.3. Clicking Update Now to refresh the notifications did not help.
