Max Backups settings not saving

[photomatix]

I'm running VE 6.3-3 and for some reason when I set the max backups (3 in my case) it's not saving the setting. This is happening on all storage devices. CIFS and ZFS. Is this a bug? I've never had this issue with old versions of VE. I'm unable to backup more than one backup currently.

I was able to set the option within the CLI. I'm guessing it's a bug in the GUI.

pvesm set <storage> -maxfiles 3
