Unable to Feed Filament from One AMS Slot

I just got an A1 with an AMS light. I keep getting the error, unable to feed filament when switching over to the filament in slot 2. The filament in slot one is working fine. If I manually retract the filament from slot 2 and cut a tiny piece off then re-feed the filament it works fine until the next switch over. Any thoughts or suggestions as to what is causing the issue and how to resolve it?
