Just make sure that you close and quit (by right-click on the icons in lower right corner of the taskbar) both G Hub and Afterburner.
I was more thinking of the C:\Program Files (x86)\MSI Afterburner\Profiles\MSIAfterburner.cfg. And you are running Afterburning Beta (4?) 4.6.2, and I have version 4.6.1
I'll update my Afterburner, and test again.
Edit: Nope to the Beta 4 version of 4.6.2. My Afterburner didn't find any update to the program, unless I opted in for Beta testing. But on msi.com, there is a last release 4.6.2... Love it when they know what they doing, and that goes for me as well
