Well it is confirmed ... there is a HUGE bug in the custom column name logic. It just doesnt work. I broke it in 1.1.0
Im working on a fix for it and will more than likely release an update in the next couple of days to fix it. Your application will download the update automatically so just start it and see if it says there is an update to check for it. Thanks to everyone for bringing it to my attention. Im gonna try to hammer out a fix tonight sometime, but no promises.
