Error:Version is already Active; activity "Set Version to Active" not executed (while trying to Reject/Activate Inbound Delivery Notification)

Hello EWM Experts

I am trying to set the process code(reject)  for an Inbound delivery distributed from ECC to EWM but its in the Inbound delivery Notification(Act.) status.

I am trying to convert this notification to inbound delivery but getting the above error.Also when I try to reject the delivery ,I get the  error(Activity "Reject Change" is not permitted; reason: status "Version" has value "Active").

I want to close this delivery in ECC with zero qty without having to undistribute the delivery.

Thanks for the help!
