WordFence options defaulting back to 5 minutes

Hey Everyone,
I am using Wordfence on a quite a few websites which has been great for preventing people from hacking into our sites but as of late we have been noticing a few sites have had their options for ‘Count failures over what time period’ and ‘Amount of time a user is locked out’ defaulting back to 5 minutes for both when they should be set for 6 hours and 1 day respectfully. Just so its out there this has happened to sites that are between 3.8.6 and 4.0.3.
Has anyone else noticed this issue? If so, has anyone found a way to make sure these options don’t reset. Many thanks to all who assist.
