    Your issue may be with the timing of when your data is put into the dataLayer and when the tags are firing. The tags may be firing before the necessary data is available. The dataLayer works in a stack-like format where information is only available from the point it was added onwards. So, you may need to adjust when the purchasing data is pushed to the dataLayer.
