This happens when you get logged out and then log back in. The reason is the way Joomla! handles message display: we are only allowed to add messages to the message stack. We are not allowed to get the contents of the stack* which means that we can't check if the message is already added but not yet displayed.

We are not going to fix this since System Restore Points is scheduled for removal from Akeeba Backup 4.2.0, to be published later this month or early March, as we announced a few months ago when we released Akeeba Backup 4.1.0.rc1. Let me remind you of the changelog message we added there:

~ The following features are deprecated and will be removed in a later version: site transfer wizard, system restore points, extension filters, lite mode, the old Amazon S3 integration (there is a new Amazon S3 integration which has replaced it)

* In theory we can view the contents of the message stack using a technique called reflection. The problem is that it relies on the internal representation of this data in Joomla!. In other words it depends on the EXACT version of Joomla!.

It was a feature that never worked really well from Joomla! 1.6 onwards. When it was introduced (in the days of Joomla! 1.5) it was really possible to take backups of individual components. Every new Joomla! version added new features and new complexity which made it really problematic. For example, if you have an extension distributed as a "package" type extension (pkg_something) and uses Joomla! categories, or ACL assets for its individual items (not the entire component), or Joomla! Tags, or Joomla! version history, or Joomla!'s UCM features then it's impossible to back it up and restore it without backing up and restoring the entire site. This is due to all these Joomla! features ending up being interwined and joined at the hip through the #__assets table. Thus, the system restore points feature is clinically dead. We have to ultimately pull the plug.
