MediaBay not showing "defined categories" on restart

I have an annoying little problem that hopefully can be solved. I just purchased Cubase 8, and have noticed that every time I restart cubase, the MediaBay no longer shows my “defined categories.” For example, in my Audio files I have Various -> Subtype selected. I have setup MediaBay to display “Defined” attributes, yet when I reopen Cubase this is not in my “defined” list and I have to go back into the “configure Defined Attributes” list and recheck it everyday.

Any ideas? I did not have this issue in 7.5.
