Target directory for monitor files setting missing from general tab in 2.9

We just upgraded to 2.9 and after the upgrade the target directory for monitor files setting in the general tab is missing. We had changed it to a second hard drive in 2.8 for extra storage space but after the upgrade it went back to /var/spool/asterisk/monitor. Is there a way to set this another way?

I guess I should have posted more info. we are running Asterisk Ver. with FreePBX on a centos box.

I was just wondering if anyone had anything to say about this?
