Hi Yvonne,
It sounds to me that you have your In-Queue setup in the Queue settings of Genesys. Admin >Contact Centre > Queues. Under the Voice section check In-Queue flow. If you have that set with a flow, that's what will be causing your issue. When transferring between queues, this In-Queue flow will run. But if you want any calls to be transferable outside of hours, I wouldn't setup an In-Queue for the Queue itself (Or create a separate flow that caters for out of hours).
Make sure in Architect for your inbound call flow that you have your In-Queue setup for the ACD if you decide to remove it from the Queue section.
