I wouldn't have thought a bios update was included in the control center app update. I've just now recalled that something similar happened to my VAIO when I upgraded it to Win 10 from Win 7 - I lost the ability to install the Vaio app completely and the bios became very basic. However that was a major OS upgrade - all I've done on the Aero is update and reinstall the control center app and reinstall XTU (after trying and de-installing throttlestop).
With the Aero, any bios updates are listed separately in the section of GCC which contains available driver updates and updates for GCC itself, as is the case with my other machines. There hasn't been a new bios update listed since I first got it and I was already running the most recent one. The bland looking bios I saw yesterday is the same version.
I'll do as you suggest and contact gigabyte support (though from what I've been reading they don't always respond).
