I have a number of subscriptions from BBC radio set up. From time to time on different downloads it suddenly starts downloading all episodes. Today it started downloading all episodes from 3 subscriptions.
I have a workround which is to delete the subscription, create the subscription again then before starting download select Tools > Catchup > Skip Permanently which was workable while it was happening with one subscription but I had to close Juice 3 times to reset 3 subscriptions.
I am using Windows 8.1 and Juice 2.22
