The backup plugin is sending a JSON to the back end with "Sticky" : "false" in all cases. This results in the backups not being marked as sticky.
Steps to reproduce:
Go to Backup Enter a Name Enter a Description Switch the Sticky to "True" Look at JSON transmitted to server, note that Sticky is false.
Actions taken to resolve so far: Changed Number of Backups to various settings from blank, 1 -> 999 Changed Max Backup size to various settings from blank, 1 - 1000000000
Also possibly related is that the notification popup ends up with a blank bar (no information) during many of the attempts. Especially if the maximum backup setting is set to 1.
