Downloading discover weekly shouldn't reset when I change tabs

[Gruggg]

With the new discover weekly genre filters, if I download discover weekly and then tab to a different genre it removes all the songs previously downloaded on the other page and starts downloading the new tab, if I tab back it will do the same. Seems like this will waste a lot of data and processing and should either default to download all genres or should keep all downloads from the other tabs until manually removed from downloads
