Maximum file size setting not being retained.

We have recently upgraded to BE2014 from BE2012.  I am somewhat familiar with the settings and management of the software.  I have set the maximum file size to 1TB for the NAS disk drive that we use to store our backup.  This is the same setting we used with 2012 and had no issues.  Now it seems that 2014 keeps reverting the size to the default 4GB.  I have noticed this happens when I switch from viewing one storage source to another.  Even after changing it back to 1TB and clicking "apply" it will still change back to 4GB after leaving the current storage view.
 

We are running the latest updates and service packs for BE2014.

Is this a bug in the software, or am I missing something?

Thanks for any help.
